I would really like to know your idea, you sound super enthusiastic.. For me I do like sleeve tattoos, I don't think it is a big matter, don't even think people will judge you because there are things much more "crazy" like 5cm diameter ear-tunnels. I mean I have 1cm ear tunnels myself and really like them, though when I first did it people actually did look a bit strange, sometimes even starring, but once I got over it myself everything changed.. I think it's a personal thing and if you act as if you are "special")) then people do look at you, but not because of your tunnels.
So yo, if you like, share your concept, I'd like to know
