avatar: .. seriously font sux.. looks too simple like arial or smt.. its just a bg (not yours i guess) and a black text.. nothing special
signature: .. dragon's cuted wing is waaay too noticable.. i think u could find a way better render.. borders are bit too huge u should make them like on top and bottom only (like your final fantasy sig by sof.) not all around the sig.. font its again really simple like arial or w/e .. bg needs work... well its your first attempt anyway.. just keep those things in mind and try other fonts next time..
