Its need to be cleaned up in alot of areas.....its too chaotic, you cant see tha focal point because the render is covered in effects. need to work on the colors and text.
The splatter is too much for that, you can barely see the render. I would work on your text, don't leave it as normal, keep it small (text must flow with the signature or be nearly invisible), and mess with blending modes (overlay, soft light, etc) JacK
