Tribal dragons do look really lovely when done well. If you have a good tattooist nearby go and have a chat with them about possible designs. I feel if you are going to go though the fun pain of getting one done its worth getting one you really like or that holds a personal meaning for you, even if it takes a few years to find that special piece.
Its not a great photo, was taken using my mobile phone, but this is my special one:
My friend Zyleeth did the drawing for me to use as a LiveJournal userpic but I loved it so much I had it inked
I have little dragonling on my other arm but I don't have any good photos of it online. It came off a flash sheet on the tattooist's wall and, while I don't regret it, I wish I had thought more about my first dragon tat.
