There is one glaring issue with this drawing for me, and that is the size of the hands. I'm assuming the intent was to show the hands closer to the "viewer" than the face is. If the arms were fully extended than the hands would appear as large or larger than the head. So, as is, it looks like she has T-rex arms of a sort.
I have some trouble foreshortening hands myself, and while yours appear a bit chunky the forward feel is there.
On the shading, the highlights and shadow areas between the blue and the tan don't always match up, which breaks some of the sense of form. Look for example at the breasts. The dark tan area does not align with shading in the blue.
Here's a Google image search of "hand outstretched toward camera" for examples.www.google.com/search?q=hand+o…
