They're pretty cool (mostly). When a person has so many that they lose count, it's not that attractive, but one or a few generally looks good. When they have meaning behind them, they're even better.
If you're talking about for a character, tattoos are always awesome! I could never get one though... Too much pain involved for me sad
True, but I think some people with sleeves or full body suits just randomly put there tattoos where ever and don't really think about how it should flow together. I was watching miami ink and this one guy had a full body suit and it looked like a story rather than random pieces. I love tattoos with meanings behind them. I want a rose or roses
