Interesting name for the first one...
Anyways, I like the 4th one the best actually.
The first one there is near no flow... It looks like you just threw stuff on it and left it.
The second one, is good. You followed a tutorial for the text I'm guessing..?
The deadspace one would be better if the BG consisted of more than c4ds on some gradient. Blend them into the Backround and the implement the render into them.
Fourth one looks cool. I like how you duplicated and made it stand out.
5th one... No comment.
