C&C

The text is really bad. The colours are wack, ditch the brushing+colour overlay style and get some better renders.

I actually like this style... they are all good, with the 3rd one really being nice.

1. Make the text bigger, and add some blue tracing to it.

2. Move the text to the lower right; so that it's not overlapping Kid Buu (oh, and maybe change that white wrapping to purple, might look twice as good)

3. Don't touch this one, best sig you've made yet.

they are all nice.. but the bg has too many colors and/or the color isnt placed right..
the last one is the best though.. work a little more on that and make it better..
let me give you a hint..
apply image, guassian blur, lighten..

if you get this then your sigs might get a bit better
