First of all, I think it's impossible not to notice how your style is represented in this picture. Drawing, shading and styling, it all fits to your very personal kind of art. This is a good thing, considering that you're drawing other people's character.

One thing that I noticed is that the combination of blue, green and beige gives the picture a warm, vintage look. I don't know if the character fits in such characteristics, but if she doensn't, the choice of colors would be affected.

Nice choice of typography, based on your website's visual identity, and good balance of the picture, with contrasting elements on the left and the right.

As for the character itself, I liked how the smooth coloring donesn't hide the details of her face and clothes. The shading adds volume to her hands and legs and is well positioned (no paradoxal shadows, if you know what I mean).

All in all, great picture
