personally, iwould move main render toleft a bit more with the stripe to the right of him.. with the render looking right so much, it might help the flow.
as for text, it's way too plain and coloring doesn't flow well - possibly a yellowish undertone to it?
contrast is a bit off on this .. gives it a cloudy feel.
try playing with it some to bring out the darks more - will help with depth
lighting behind AP is off, too. try to focus the lighting on a focal point - for instance, he's looking up and to the right - that would be ideal spot for it to...
