Ive a friend that just draws all kind of art with tattoo purposes and they are nice... i suggest you should find some "art-geek" and he'll know peeps that can make you LOTS of drawings and stuff.
I have a tattoo too, the "HIM" symbol. Just be acrefull if its your first one. They are very very addicitive for me. I spend 2 years with a tattoo-ache which i overwon. the art friend of mine didnt... he has 6 now... a bit too much imho...
for the remainder about tat's in general, i would say: "wait for it". even if you know you want it and really decided it... wait for 2 months or so and see if you still want it. So you know you REALLY REALLY want it
if you do have lots of tats... GO ON! knock em dead :P
and now really on topic.
I once saw a nice guitartat. It was a les paul with "wings"
Like an angel. *cant find any pic of somekind* *something like this
so... hope i helped you at least a litle bit...
cheers
