Don't listen to GP. Don't scrap it, try to better it. If your going to make a black and white tag, work on the contrast over the signature. Try not to make it look like its just two different colours have it changing from white through shades of grey to black. The effects them self seem dull and boring and the tag itself is far too flat for me.
Im with GP. Sorry. But its way over lightened and contrasted and the base effect just are not there your current of the same render is better use.
