I like it man, jus a little plain, for sum reason....u really know how to pick out text, I like it with that sig....def. not as good as ur Shrek sig...but its pretty good 8/10
wrong places for it...um try a darker grunge, make the render a lil bigger and stand out a tiny tiny bit more, instead of blening right in...ummm, maybe brush a lil more with some different brushes...
I cant pick between the last one you shown and the first one there both good...maybe a tiny bit simple but still...where'd ya get that font you used? Looks awesome 9/10
