i really like it, nice colors, there are however 2 points that i think you could bring your attention to. 1. text, everyone that i know struggles with it but on yours it looks like you tried to hide it. it is very hard to read, the colors match, and its so small. 2. border, the border looks like you made the sig then pasted it onto a new file but didnt center it right. it seems out of place on this sig and it interrupts the flow that you have put on it.
Its nice i like it, the bg has a nice flow and the colors are nice. The one sided border kinda just sticks out wouldnt go that.
