Its called constructive criticism. :|I don't think I've ever seen you say "Good job!" or "Nice work!" without criticizing. The background is "boring", that's extremely subjective. "The text placement is bad"? Really? Is there a correct way to place the text in a signature? No. Apparently, for most of the people that have seen this signature, the text is placed OK. Just because you don't like how the text is placed doesn't mean it is placed badly.
Stop trying to fit art into rigid rules, this isn't Neoclassicism.
On Topic: I like your signature, good job.
@Downie
I'm not saying its bad. lol. I just said that you gotta keep practicing. ^^ My signatures were alot worse when I started.
