oh, wait! i see the rest now!!!
#1: i like, but the left side looks a little empty, and sora is a little blurry, but it's nice.
#2: Wow, i like that picture of Cloud! Great work!
and #3: The background's a little blurry, but you have a great over all style!
(do you use photoshop or GIMP?)
One last thing: Some of those are a little big to be used on this forum as sigs, make sure they're only 500*300, k?
