A few problems, but still alright
There are a few anatomical problems with this, and I know I'm going to get a "ur an as$hole. i don't care" response, but I feel like they should be mentioned.
One is the wrist. I don't know about your wrist, but normally they don't bend as much side-to-side as they do up-and-down. The way you have her wrist bent makes it look like her bones form a spiral. Even if the intention was to make it bend straight down, the lack of flair at the base of the palm and the incorrectly lengthed fingers just make it look more like an octopus tentacle than a graceful feminine wrist and hand. Wrists can be sexy and graceful. You should practice those.
A small note should be mentioned about the calf muscle. Unless you're drawing the hulk, you shouldn't make up muscles. And as it is, it looks like the leg is bending at an extra joint.
Last, and most important: Boobs don't attach at the collarbone. I don't know if you've ever seen any, but they usually attach about 2 - 2.5 inches down from the collar bone, and are affected by gravity. I know that you could say "shes wering a pushup bra, b1tch," but that has to be one hell of a pushup bra to push them up to the collarbone. Even bras with an under-wire don't change where they attach to the chest, it just brings them up to that level. Looking at the preview images for you other artwork, this seems to be a problem you experience a lot. So I recommend taking a life-drawing class, or, even cheaper, just finding pictures of naked models on the internet and tracing them. It'll really help your boobs look more realistic and help fix your anatomy in general.
So, that's all I have to mention. Overall it's not bad - the proportions and the clothing folds are adequately executed. I would have given it 8 stars, were it not for the aforementioned anatomy problems and for the fact that this is still a sketch. Congrats on the front page and all.
