Top one: Abstract, but the text is a little hard to read. 7/10 Bottom: Don't like the guy in the pic, but nicely done. 8/10
9/10 I love chaotic sigs. Note to the following poster: Ignore the last little thing in my sig. It's just a 2 min. paste job.
First 7/10, renders have nothing to do with each other, but the BG and main text are aight, though I dislike the quote text's color. Second, I don't like the white quote text still, it just doesn't look right, and on this one I'm not a big fan of the main text, though like the first, the BG's aight. 6.5/10
