Got a 'Straight Edge' and a crucifix on my chest, a quote from E M Forster on my left arm, the beginnings of a back piece on my...um, well, back. And in FOUR days (!) I am going for the first session of my sleeve

Very excited. If I had any legitimacy in offering advice, it would simply be to know what will be important to you in years to come. It really can't be said enough, are you REALLY gonna care that much about your local sports team, or that kick-ass band, or your current ladychum in 10 years? Some things stay with people for life - for instance, I think Hubilub will probably still love Blade Runner (what quote by the way?) and A New Hope in years to come. Good choices.
I think it's the difference between tatts representing what you like, and tatts representing what you are.
