Banner's not too noobish. The worst thing about it according to me is its JPG-format, hinting that you should try to make the file smaller some other way. The banner isn't the best I've seen (I'm not gonna mention the mistakes, because I'm not too good either), but as it's basicly the whole sig itself, there's not much more to base a rating on.
6/10.
Psychic powers says: Mine will be rated low, because it's under construction, and I can't fix it right now XD
