Yeah, it's really good, I don't really like where you've based your focal point, but the rest is good, text might need some work too.
Thanks for the comments, I'll work on the text a little and I might try bringing the focal point to the left a little.
Ermm.... it's a vector brush only signature and you can't really have a vector signature without the arrows ? Besides there's only 3 tiny ones and you can hardly see them. And I chose the colors that were featured in the original render which was quite colorless. I don't mean to sound arrogant but if you're going to give me feedback make sure it's something I can work with. All of the other people have been pretty helpful with their criticism. I don't know why I'm posting this because I can tell you're probably one of the people who take one look at the signature and post a comment in order to get their post/credit count up. More feedback please.
