It actually looks pretty good, except for how it's really really blurry on the left and right side, other than that good job.
This is what I mean.... Gosh... Everything's great man. Personally I think it could be a bit brighter with the rays of light shining down and such, but the whole focal is in perfect position and the colors are nice too.
Great coloring, depth, and text. But I see a lens flare at the top which is pretty ugly and a little distracting. If replacing it with a white soft brush on low opacity doesn't work, I'd just take it out, because the rest of the lighting flows, unlike that flare.
