The first one is better. I’d discard the second one. Really, you must change the hair and get the pics redone. I’m saying that as a horndog who genuinely thinks you have potential.
Sorry, but you’re coming across as butt-hurt that you didn’t get a lot of glowing responses. I agree it takes guts to post pictures out online for people to critique, but people critiqued.
Most people focused on technical aspects or things that you can change (how your shoulders are held, etc.). Some people were unhelpful (you can’t change the size of your eyes, like you said) but the vast majority of the advice was constructive criticism.
If you can’t take this mild heat, I have no clue how you’d survive in the acting world.
Both pictures:
It’s a woman posing for a portrait, possibly to be used for a dating service. She’s probably around 37, fairly pretty, nice enough figure.
The smiles are not real (no eye crinkles) but aren’t disturbingly phony.
Picture 1: slightly shy and a little flirtatious.
Picture 2: Outgoing and touch brassy.
I prefer the first. The smile is a little better.
Posted without reading other responses. (I’m a pro photographer.)
Without looking at any other responses:
I would guess her personality as the same for both photos: Outgoing, fairly confident, overtly friendly, but maybe with a little bitchiness behind it.
In both photos I see her thinking, “Why is this guy taking my picture, I wish he’d leave me alone, but I’ll make it a nice photo anyway.”
Photo 1 age: 28
Photo 2 age: 25
After reading the rest of the thread, I find that I really suck at guessing ages.
Or maybe you just know a hell of a lot of people who lie about their age. 
Basically. I’m a bit miffed that any comment to the OP that is less than utterly glowing is met with a snotty quip that more or less boils down to, “YOU DON’T KNOW THE INDUSTRY, OK?!”
Ok, all your actor friends like them. Most people here obviously do not. It’s your actor friends and producer friends who will get you jobs, so just close the thread and go with that.
Well, for what it’s worth, I am in the business, and I don’t think they’re very good headshots either. Looking at the other photos on your website, I think you’re a lot more attractive than these two pictures make you seem (I especially like the second to last one on your resume page). Also, that exposed brick in the background isn’t helping any.
I know I’m not answering your specific questions, but then, neither will a casting director who’s looking at hundreds of headshots. And I, along with everyone else here, am only trying to help. But I think you can do better.
Well, that seals it. Considering DooWahDiddy’s extensive experience, you’d be a damn fool not to take his advice.
Do a search if you want to know what he does, but he sells himself a bit short when he discusses his work on this site. His resume is more impressive than he lets on.
Ok. But, why couldn’t we just answer the question. Seriously. Why couldn’t we just answer the question in the OP? Why did we have to add all that other stuff?
Well, personally, I made the mistake of reading the entire thread before posting my reply to her questions. After reading the thread, my initial response changed and became biased by her terrible attitude in this thread. So, basically, I couldn’t give an unbiased answer at that point because the OP came across as such a brat in her responses.
Everyone else? They’re just bad people. Me? I’m awesome.
Wait. What?
Aww, you make-a my face turn red. Thanks. 
I think I play too much computer game. I saw the title and thought ‘headshots’ as in killing people in the head.
You should play more games that improve your reaction time.
Kath Sex-ample II is sexier than Kath Sex-ample 1, if that’s what you wanna know
It doesn’t matter how well you know the people you presented these photos to in real life. (Boy, that’s an awkward sentence.) If you asked for feedback face to face, or if these people have any chance of seeing you face to face at some point in the future, you’re not going to get entirely honest responses.
In fact, if you had come right out in the OP and said that the photos were of you, you probably would have received much gentler responses. You received naked honesty because folks in this thread thought they were critiquing a random person.
What sort of work are you looking to get?
My inputs from a photography perspective…
I think overall, your poses and approach to the camera are good, and you are photogenicly positive. I don’t think your photographer gave you a good session though.
– The brick wall makes it look like a generic Sears studio backdrop. The bricks are also the same color-space as your hair color, and about the same value as your top, so nothing “pops”. You kind of get muted into the background.
– The lighting is too diffuse and ambient. You have great hair color and it isn’t being shown to its best. A sunny outdoors approach would be better.
– Your arms are just hanging, only biceps visible, and your hands are out of the shot. A lot of personality and attitude can be shown in the forearms and hands.
– You mentioned your large eyes, these are a good feature. Due to the diffuse lighting though, you aren’t getting any shine or specular highlights to them, when you could get a really good sexy Bambi or anime effect going for you. I also think better eye shadow/liner would help but don’t know enough about makeup to know more.
– Your hair has too much product in it, I get distracted by the “wetness” of the style. It looks more like you were trying to tame bedhead in your rush to get to work instead of a deliberate styling choice. Needs more diffusing and body to your hair.

What s/he said. Really odd angle, and I’m not connecting with her eyes.
Your SDMB-linked website says you’re a professional photographer and actress. So your sought-after advice feels a bit disingenuous as you sell your retouching and photo taking abilities.
The story I see is a cougar trying to play to her boytoy taking the photos. However, she is trying too much to be whimsical and impish, but she’s a bit too old or maybe just too hard to pull it off. Age, about 40. It’s probably just the lighting, and I bet woman is much more attractive in person.
