i find it is far too contrasted and the dbz charecter kinda ruins it..
i think you should experiment a little more with picture placement, this also goes for your current sig (which is pretty good i must say) it just luks as if u throw it on anywhere.. theirs never any harm in experimentation..
also work on ur typo skills, try and find a few new fonts and try and make it flow with the sig itself...
on a final note it may luk like your trying to achieve too much, but hey this is just my opinion.. i can see you got alot of potential to do better..
