Please bear in mind: I am not an editor, a publisher or even a writer. I “write” for myself, but mostly I’m a reader.
There’s a few things that jump out at me to start off with. Number one is your sentence structure. Even without you mentioning that English is not your mother tongue, it reads to me like it has been transliterated from another language. You may want to try getting your hands on an english-language style guide for help with sentence structure and grammar from a technical standpoint.
Number two is your repetition of certain phrases - “three years and six months”, “(while juggling the/her dagger)”. You need to find ways to work this information into the story without repeating the same lines over and over again, and especially without resorting to repeated use of parenthesis. Parentheses. Brackets 
For example, in the first paragraph you use “three years and six months ago” twice, then again in the fourth when your character is reminiscing about her friend. You’re obviously trying to show that time has passed since the character was last out in the lands as a warrior, but the exact nature of the time description, and the repetition, leave it feeling somewhat stilted and unnatural.
If I may, I’ll take a stab at how I would write the opening paragraph:
“Kristen’s sword hung on the mantle, sheath dusty with disuse. There was once a time when gripping the weapon would have reassured her, the weight of it, the strength of the steel in her hand filling her soul. But that time had passed. Now, with her home filled with the presence of her beautiful daughter and faithful husband, she had no more need for that reassurance.”
Obviously you’d write it in your own way. But you don’t need to tell your readers exactly how long it’s been since the character last fought a battle. But you can show them. The sword is dusty, obviously it’s not been held for a while. Her daughter and husband have supplanted it in importance, so she’s been spending her time on her family, not fighting. Things like that.
I guess the big thing I’d want to see if I were to continue reading your writing is for you to follow the saying “Show, don’t tell”
You keep telling me that Shara likes to juggle her daggers. Yep, got that already. You’ve told me many times that it’s been three and a half years since Kristen last fought alongside Ioeric. Great.
But then we move on. When Ioeric is talking about her lover, you manage to show the prejudice against Orcs and Half-Orcs by the way that Sharna takes the news of Roland’s heritage - She’s disgusted. Even after meeting Roland she’s still left with a bad taste in her mouth. But you haven’t told me that outright. You’ve shown it with her choice of words, the fact that she’s still calling him a bastard even after he’s shown he’s nothing like the other half-orcs she’s known. Kristen notes he’s filed down his teeth, perhaps in order to further hide his orcish blood. I liked the way you handled that.
You’ve set up an intriguing fantasy world, and I’d like to see where the story is going to go. Thematically, I quite like the story. I just feel that you need to concentrate a lot more on the technical aspects of grammar and sentence structure, how to describe a scene without actually drawing out every little detail and without repeating stock phrases, if you’re wanting to write in English.
