Wow. I love the atmosphere here. Its so dramatic! The blockiness looks tremendous and the colours are so rich! The lighting from the purple on the black just looks great. Guess who's won my vote?
I really love the feel of this piece; great background! Awesome hue shifting with some great blocky-ness! Totally great!
Oooh, hypnotizing colours spiced with the idea of creatiness (creatiness, is it written like that?). Beyond that the work in it self is done very well and I gave it 5/5.
Lol, I never had much hope for one of the first three places, but I still feel a bit crushed. 
On the other hand, I expect more good challenge entries to be entered before the deadline, so I'll just shrug of that feeling.
Anyway: Good job! 
Really interesting. You certainly will be the winner if no one posts anything better.
