Oh dear...anatomy errors are rampent
I will say that is a lovely hat, and the shading isn't too bad, but the anatomy is rather...horrible. Needs lots of work. (this will pretty much be the same as what Enact said, so feel free to skip some bits of this) First off, a woman's breast would never be that high, even if they are pressed together. Secondly the shoulders are a bit to...broad would be the word I guess. For most women, they have a shapely figure and soft/rounded shoulders. If they're too broad, it kind of makes the waists and hips look too small. Speaking of which, her hips do look a little too small there.
Lastly I would choose a color scheme for the background. Instead of green, purple, cyan, and whatever else. You should use red and green, possibly with flicks of yellow or orange to make it look warm and slightly inviting. Blue in my opinion just doesn't fit it.
Other then that, the picture is okay, needs work, but then again that's true about all art work isn't it? Keep trying, and I hope you had a happy holiday.
