Hey Emma, Jeff here ok here's my two cents. Now I've noticed that you like to use hard edges which is great but the lines you use to depict the contour of the face and body aren't there. Things seem to be shapes attached to other shapes and don't give me the sense of how it's constructed. I personally like to start with a sphere when drawing the head and then work out words and sculpt the form. with hard edges though they tend to lose their excitement if it's over used. So I might try to put in some soft shapes to help accentuate them.
