Naughty or Nice?

Yeah, I'm just gonna upload this to DeviantArt because it's the very first thing I've ever done with my tablet.
Yes, I've improved in drawing since the last time I posted one on here, which was forever ago.
Using Photoshop CS3 for the sketch, and SAI for the lineart and color. I still don't really know how to shade or highlight parts of a picture. Also anatomy. That's a thing.
Critiques are open. I'd love to have some advice on how I can do better. Just don't be rude about it.

I am more active on my Tumblr, so you may want to follow that instead of on here: shake666productions.tumblr.com
