Ah yes, the best character! You certainly drew her very attractive. There are a couple problems though. Firstly, we're not shown the thing she's resting her leg on, so it looks a bit weird. Then, her left thigh looks a bit too...lumpy, if that makes sense. And if she's not leaning on something else with her arm, then it must be a bit too long. I also felt she was missing her attitude, and that's probably because her facial features aren't quite right. The eyes are nice, but the nose always looked prominent on her face. Her, I wanna say, cheek freckles (?) could also be more pronounced to make her less generic.
Overall, your art looks nice and smooth, but I think you might need to work on anatomy a little and be careful with facial features of characters. Try adding some background details, too, to make things more lively and immerse us in the world of the source material.
