what did you do to Edge's psd? look at his face.. does he look like Edge now? lol..
Dont over-use the blur effects. Try use the eraser and remove teh ugly part of the blur effect so that it will mix well with the bkg (in a good way).
Rated R Superstar on the first sig is not clear at all, it looks like a dirt or some gfx mistake done there.
Now always remember that as you are using one psd in this, always try to make it stand out more than what you did. The focal point and centralization should be achieved.
