i think u should remove the border andedit the text a little bit but i like the background dude well done paparoach is awesome
It looks nice but the effect above his left shoulder looks pixelish. I would also remove the outer glow around the text. Maybe lower the dark/bright difference between the left and right side of the sig.
The background is okay but it's really oversharpened imo. Try to work on the text too and on the colors. Just read tutorials and after a while, you will find it really easy. Good job =)
