Lol sry I don't know why I'm advice reatarded lately. I would say work on teh coloring and depth. If you blur the sides a bit it will help create some depth and make it look more focused into your sig in teh middle. Also the coloring seems pretty..odd I'm not exactly sure how to put my finger on it. Maybe try seeing if you can get it less saturated.

And last but not least text. Maybe next time try a smaller text or something. The actual font you ahve isn't too bad but like i always say, default fonts are usually better..
Overall not bad. Sry for teh shitty comment before.
