Well, I love all the stuff that looks 'sketched'. (The logo looks excellent btw). Everything that looks like it was stenciled and sketched looks great, but then it looks like you took 2 or 3 very basic brushes, stuck them in with the sketches, and added a gradient. It's a very nice piece don't get me wrong, but I wish the sketching would of stayed consistent throughout the whole piece, instead of adding in vector elements/brushes

nice colors!
