It's your skin, dude. You have to put in it/on it what you feel is right, and screw what other people think, dig?
I put them where I did because that's where I wanted them to be....but I'll agree, I did compromise a little and put them places that I can cover up if I have to. But still, I got what I wanted, where I wanted it.
Now I'm all excited at the prospect of getting my 'wings' done on my shoulder blades!!!!
