Anatomy...
Colors are well made; and used; I like them!
But you should really keep an eye on
the anatomy.
When drawing women, it's all about
curves! (Sorry if that sounds perverted)
Also, the eyes are a little out of place,
they should be closer to the nose.
Also, try solid backgrounding.
THis means to actually have an image
and not an abstract background, they
really give your drawing a better look.
Hope this helps!
