Awesome vector tag :O The color scheme looks really good too.
Kinda reminds me of Lovebeat's style for some reason though, heh.
Anyway, the vector on the left side seems awkward imo. The positioning of the vector blocks too much of the charming points of the character, the camo headphones. And then the vector's flow doesn't look natural to me. :/
I would probably re-do the vector and have it behind the character layer. Maybe clip-mask a little this and that (clipping repeated patterns/textures do great!) to the vector and help the character to pop out a little.
As Jagan said, work on it and give it some time, then it'll be quite awesome.
Lol, so you were the one who made this!
The sig is so gorgeous, I thought a really-really-really good sig artist did it some time ago! I could never quite find out who made it until now! xD
