The illustration is absolutely beautiful, and flawless, but being a designer & type lover I can't get past the type. It's not incorporated well into the piece. It looks like an afterthought, and doesn't really mesh with the style of the illustration. You've got a nice-looking signature down there, use those skills to make some awesome hand-done type!
Btw you are an awesome illustrator. I love the element of the halftone popping out in places. It really makes for a unique style.
