its okay, i don't really know about the bright white at the top, for some reason it brings my eyes from the focal, and like others have told me, that if you don't know about the text, then don't put it in. but thats just my opinion ^_^
The lighting source looks a little too fake. It's there, but it's not. If you know what I mean. The render is too colored. It looks a bit amateur. It looks like you made the background, and added the render, and from there made everything match the background. Like poster number 1 said, if you are unsure of a nice set of text, leave it out.
