Pretty good!

The only thing that strikes me as off, is the hand closest to the viewer. If you want something to 'pop' out of the page more and to appear more 3D, you've got to foreshorten it and utilize line weight / scale so it doesn't end up looking flat. Her hand blends in a lot with her torso, so if you were to make the hand about double the size, and maybe thicken the lines, you'd probably have a little more of a realistic feel going on.

Either way, just being overly critical -- take everything I say with a grain of salt. This still beats the hell out of the digital stuff I was doing when I was your age. Keep on keepin' on.
