Low Relief Painting - Thai Chicken!

This is a little experiment I'm doing for my texture class; can you paint good lighting in b/w then apply it over the textureto fake a low relief sculpture? Well this is what I got. I must say, I really have deep respect for art in my country. Can't imagine how they came up with this for a chicken. Let's just say that they were lucky I wasn't the one designing these things for them. :3
