Who said I can't use my imagination? I simply said that I couldn't think of anything to make it very good. That doesn't mean I didn't try....But, on topic maybe try some vectoring tutorials?
Show me one signature where you used your imagination. Something different from all the others you've made. Your signatures are just average. C4D's, and a render. No clever use, nothing really interesting, they just look pretty, which eventually anyone can mount too. Wait a second. There I go again. Umm... nevermind.
