What do you consider to be beautiful in a tattoo?

I would just like to know what people think about this question! I'm coming to find that I really like well done bird tattoos! With a lot of color and flow they just seem to call to me! Also, I think a good tattoo needs a good background...personally I like ones that have flowing water or something in the background...obviously it depends on the subject matter though. I've seen some really great ones on this site that are just full scenes, background, foreground and everything! ANYhoo, what do you all think! Dana
