#1 composure (of the first one) is fair good (i am assuming that you designed the background and blended it with the image to the right), the text's font and color sucks though. the avatar (if you designed it and it's colors) is superb.
#2 bland, almost novice
#3 the black background enhances it a lot, the green makes it look eerie - very cool, however still looks like it was created by a beginner
