The shadows look too much like pastel work to me, id smudge them out a little more so there's less of a grain (don't smudge the render though, it looks good to me), good choice of text, nice coloring and concept..
8.6/10
Nice job unknown!
Not bad, lighting is a bit off.
Text could use some fixing up.
Dark.
Still not bad.
Needs to go left to right.
