Well to start off positive, I like the background, but there are a lot of things I don't like.
1.) The render doesn't really blend with the background.
2.) The size is huge
3.) The text doesn't really fit the theme of the sig.
4.) I dont like it when people add a stroke (outline to the renders)
5.) The lines over the render don't look to good. If you are gonna put scanlines or something similiar, I believe it should be over the whole sig, or at least the whole background, not just the render.
