The links seem a bit tenuous - British / Italian, Cafe Racers / Pirates. I don't get it at all.
sp -British and Italian should always have capital letters.
The site seems kind of artsy which I like, but then I just don't get it which switches me off. You need to get lots of feedback from others (strangers) to make sure enough people do understand it or you'll be wasting your time.
The cracked pic on the first page is interesting but it dates your site by proxy.
I think I would like to see more explanation in plain language - no bull*hit and maybe some pics of bikers wearing your shirts to earth my brain a bit. I read and understood the Father Bill script and I got it and I'm okay with it so now I can decide whether I identify with it enough to buy it. You can only ask people to buy into your idea if it makes sense and they understand what you are all about. If you don't get this right all you will get is an obscure little website and lots of heartache. The shirts are nice. Good luck.
