well these are like 3,4 years old cause i haven't been working in photoshop for ages;
this is all i managed to find from my old forum, i might do few signatures again >_> (probably not)
They are all old as fuck:
couldn't find anymore cause other were uploaded to imageshack and links got broken over time i guess
most of them are done with help of some tutorials i think or something like that since im not rly that good in photoshop xD
