Sorry it took me so long to do this! Been out of town several times in the past month, and though I had my tablet with me, I couldn't get myself into the right mental space for critique.
SkyfireGorgeous gorgeous green and red-gold and light and smile. Really can't say too much except for some nitpicks in the lower-half of the body.
1) Foot: Afke already mentioned this one. Toe area too large vs slightly too small heel
2) Hip: A leeeetle too big. I'd pull it in a smidgeon
3) Knee area: (I think you would have caught this one yourself in time) knee and calf were too small
4) Leg angle: You'd need some handy-dandy digital transformation for this. If this isn't something you don't do already, lemme know what program you use so I can point to the right tools. Basically...her leg isn't going to hold her weight too well in that angle. Need to bring the knee down under her a little more, which in turn lowers the bottom leg.
Of course, in that sort of position there are a lot of subtle ways it could go. #3 and #4 are just one suggestion.
After:
Chitter1) Tree branch: To help with the sense of her leaning on it, I'd skim some off the top. (I also felt that the reddish color was a little too vivid, and fighting with her own colors a bit. So in the version below it looks browner. Not sure if I really did the right thing, though. )
2) bosom: Move the cleavage over the right a bit, and define how the left breast interacts with the arm a little more. I'd also show a little of her torso under the breasts, to bring it more in line with where her elbows are resting.
3) hips: bring the left outer thigh in and the right inner thigh in.
After:
Alternatively, I tried it with her leg jutting out:
