I think this is in the right place but then agin, I could be wrong.
I'll be frank with you, this isn't a signature. More of a very small wallpaper. The design seems kind of choppy. There is no really main focus(not that I can tell) and just kind of seems like you stuck images together. The Axel image is kind of...small. Blurry so to speak.
It isn't all that bad but it defeats the purpose of being a sig. Kind to make something a bit smaller. This makes me think of my first sig. Ah...It wasn't all that good but it was a start.
What matters is that you keep practicing and improving little by little. I know I still have a long ways to go!!!
By the way what program do you use to this with???
