Pretty awesome, though the positioning would hurt like fuck as a tattoo.
Yeah, thats the sensitive inner arm skin isn't it?
I don't feel like people could appreciate it on your inner arm, as its facing inwards and to them would be upside down? But if its more for your own personal enjoyment then I guess that doesn't matter so much.
I'm guessing you've had tats before so as long as the tattooist can do it justice I say go for it, and post pics!
