The background looks rather simple, it is not at all. But that's because of the dark colours.
The blue one looks cool, but you should edit your first post so more people could see the other version, not many people like to scroll down.
I like version two, because I don't think it should have too many colours, nice one.
Simply amazing, I wouldn't say look at tutorials, because I don't think you're a beginner at all! Best I've saw today.
Very neat, I like it. Goodjob!
Love the effects near the head, makes it look like he's moving very fast.
Kind of hard to see because of the intense colours, love the text thought. How did you do that?
Not my style, but it is a good signature. Just personally don't like it.
I don't really like the size that you've used. But it's overall a good signature.
So far what I've seen of you, it was all good. You're an excellent designer. This one is also top of the notch.
Did you win? I don't like the text myself.
I like the size of version two, but the teddy is cool on version one :)
Very nice, only the centre is a little to bright, I know it should be like that. But make it a little less bright, good signature!
Unique! But not my style, the colours don't fit the evil vader in my opinion.
I don't really like it, I don't know why. Sorry!
version two is cool, I like the colours on it. good job.
Awesome! It really is, good job!
Very nice, all the versions are cool but I prefer the very first one.
I like the colours that you used, it fits really well, but you should do something about the white space.
Nice one, I think the no colour one looks better.
Version two is really amazing, greatjob!
First version is better, that's because of the colouring.
I like the colours on version two, good one.
Our hero needs a good signature, good job.
Really neat but, what's the white block at the right?
