The legs look kinda weird here, I feel the leg that's screen right should prolly be further to the left just a bit. The shoulder on the right could connect to the body better, at that angle it would cover up the neck more and take more prominence, with how it is now, it doesn't rly look like she's turning her head around. I'm assuming you've prolly done some figure drawing, so just keep at it and you'll get the hang of these sort of poses. Go on Nub, I beliieeeeeve in youuuuuuu!!!
