Please keep in mind that I went to an art school that employed a pretty vicious approach to critiques, mostly designed to help the prospective artists to learn to take criticism of their work without taking it as a personal attack, so please don’t take any of this personally…
OK, here are my thoughts:
As a new comic, I think that it would really benefit the reader to have a few episodes simply to establish the relationships between the characters; maybe show the family in the car as they arrive at the house, and maybe the brownies are watching them arrive from inside the house and commenting on the new arrivals, referring to each other by their names so the reader can get a sense of who they are and why they’re even there to begin with.
There’s a lot that I found confusing without the additional explanations of the characters on the Web page. For example, it wasn’t at all clear to me in the second strip that the girl with the pet carrier was supposed to be the daughter of the couple in the first strip; I thought maybe the woman had gone outside the apartment/house and the boyfriend/husband was calling to her from inside, and I had to read the character descriptions on your page to get a bit more of what was going on. If I had just the first strip to go on, I would have thought that this was a young couple who had decided to move in together and that they were unmarried and had no children. The art style contributed to this confusion (more on this later) and I still didn’t get why the female was carrying a pet carrier with a human boy inside it, and why she would be surprised at him coming out of it. Did everyone in the family just not miss the kid during the trip to the house? They get out of the car at their destination and the boy is missing, but they just don’t notice or care? Combine this with the unnamed (in the comic thus far) brownies and I thought maybe the kid was actually some sort of leprechaun, which would explain the girl’s surprised reaction and his strange behavior somewhat.
I don’t quite get the brownies’ skeptical reaction to “peace?” either; are they skeptical that the new family will actually be peaceful, are they skeptical of the idea of “peace” (some Fae folk in myth and legend were notorious for creating havoc and mischief) or what? Are they going to be hostile toward the family for invading the space they are living in? Are they going to drag the kids down to the basement and steal their teeth to eat? It might be better to establish the family first, then introduce the brownies and explain some of their motivations and relationship to each other. Are the brownies siblings? Mates?
As others have said, there’s not a lot of story or characterization to go on yet, so it’s hard to say much more. From the character descriptions, I can imagine the potential relationships and stories that might come from it, but if you take the perspective of a new reader who just wants to enjoy a fun story and characters, there’s not much of a “hook” in these first two strips. I think establishing that “hook” is one of the hardest things for a new strip to achieve, so don’t be discouraged by that, just keep trying out different approaches and showing your “test audience” the strips until you get the reaction that you’re looking for.
Now, about the art:
The manga style employed here really isn’t working well for me, because there is a tendency to make the characters look very young and similar to each other. If it weren’t for the goatee on the guy, I would have thought that he was in his teens; same goes for the boobs on the mom being the only “adult” characteristic. Even with the goatee on the guy, they look like they might be a couple in their early college years, not parents of two kids, one of which presumably is a tween. You might be able to get away with that more if you have the aforementioned establishing shot of the entire family together and some dialogue that shows the family relationships. I’m not saying you need totally realistic artwork here, but it’s a bit confusing when everyone looks so close in age that they could all be siblings.
The artist could benefit from learning and employing some basic perspective drawing skills (here’s a good start) ; he/she will learn a lot that will translate into artwork that is easier to “get” and put the characters in a more believable environment. Some successful cartoon artists get away with little or no perspective drawing in their strips, but since a big part of your story has to do with the house (the house is actually a named character! I like that bit.) I think it would really behoove the artist to pay attention to those details to give the house more character and visual “solidity” as well.
Don’t be afraid to rework the intros and artwork and character designs for a while until you get the desired reaction when you show the strip to someone who isn’t familiar with the whole thing. Ideally, your readers should be able to pick up on who is who and the basic idea of what is going on without having to read character bios on a separate page. I think for a character-driven comic strip, that is very important (well-established characters and relationships are important in a comic like For Better or Worse but not so much for something like Frank and Ernest which is more of a joke-based comic.)
Good luck and please keep us updated!
