Honest opinion in 200 characters or less because I'm tired and going to bed now: Colours are bland and uninteresting. Text isn't hard to read but it's almost lost in what's behind it. The effects and such are nice but aren't very dynamic. Overall, I find it pretty boring looking.
He was a dark character but in the end, he turned out to be a goody goody of sorts. You should have incorporated that into the sig, IMO Other than that, I like it.
