I've seen lots of entries from the Tomb Raider Reborn contest and this is one of my favorites. I like the hunted look in her eyes, and the way her torn up clothes and wounds don't look as overdone as in some other paintings.
Overall, this is a great work! But the brown is too musty and.. dark? I don't know, maybe brighten it up a little, or make it darker, it seems like it's missing just a tad more detail in the bottom left of the composition. Again great work so far!
