Shadows in the correct places?

[JonHop]

I like that you're going for a cel shaded look to this, as far as I can tell the light is coming from the right which means the shield would be darker on the side where the arm is as the light is hitting the other side and there would be a cast shadow on the body from the shield. I think the bottom part of the neck would be catching a bit of light also, not shadow covering it all. her left leg would also have a shadow where the two parts of flesh meet. Think about not just the main shadows but after them being laid in double check if there are any places where there light would being blocked by the figures limbs etc and also the items the character is holding.

Also Psycho time is right, keep working on your anatomy skills but keep doing your own work as well and you'll see your drawings improve a lot from your studies :).
