For a critique I ain't got much for you. Just two things, one of which is probably irrelevant. We'll begin with the irrelevant one. The dress you've got her wearing really shouldn't cling to the breasts or leave them that defined, I'm afraid thats just not how most clothing works apart from black laytex. Of course you also got a nsfw version hanging around somewhere ( at least I assume you do) so this might just be a style choice.

The second difficulty resides in the top leg. Because of various things, you never actually show the leg connecting with the rest of the body and this creates a very slight, disjointed sensation. A bit like the leg is a sticker that you just stuck on. Like I said, this is very slight and probably because I looked to hard to find something to critique. As for something I feel is a problem, we don't really get the impression that the upper leg is resting atop the bottom one, somewhere along the thigh there should be skin that squishing and spreading outward. Cross your own legs, see where the two limbs cross. Mine cross more at the knee then in middle of the thigh and there's not that great of a height difference.

So that's all I got for you. Like I said, one large-ish difficulty and one near inconsequential one. Regardless, I hope this helps and if not, then my house was on fire and I had to do a rush job of the critique.

May fortune favor you.
