Awesome! 8D She's my favorite troll, and this is my favorite scene of hers (and her epic chainsawing right after). I really like that you made her barefoot for some reason, and it makes me wish she were barefoot in canon. :b
With the way her arms and legs are positioned (though I mentally assumed her right foot, left from our perspective, was the one in front), I could have sworn she was doing some sort of odd dance at first glance.
It's weird, I feel like I can't get this to look right. It is her right (our left) foot in front, and she's taking a step forward. I sketched it out without the skirt and it looked fine! Once the skirt was added, it just looked bizarre. :T
In the case, the position of her left foot seems...odd, somehow. It seems less like she's stepping forward and more like she's sorta stepping sideways. So maybe they legs are crossed too far? Other than that, the position of her hands (both up front) and her closed eyes don't really imply she's walking. Like I said, it looks more like she's doing an odd, sad dance to me, lol. But other than the strange positioning, it really is a nice picture.
