I really like this style of yours! The background is amazing; it looks like a combination of a traditional oil painting and the game's minimalist style. As for Ammy, she looks more like a real wolf here - also, her head is similar to the heraldic wolf of the Stark family from the Game of Thrones series.
Really, the only critique I have of this is that Ammy's other ear seems to be invisible, and her eye looks just a little too long and slit-like, though I realize this could be a stylistic choice on your part. Also, the sheer amount of lines for the fur on Ammy's head and neck make the rest of her body look rather bare - maybe less lines in the middle of her neck area would make this look a little less odd? (Again, could be stylistic, so all up to you)
Basically, this is really good and I like it a lot, so great job!
Thanks so much for the critique! It really did help a lot. I'm glad you like her head, because I didn't think anything looked wrong with it. But that's coming from the artist. As for the lines, I agree. I guess I just never noticed it before. I'll look into editing the fur and making her look more like in the game.
