Maybe GP is not the target market and I guess I'm not either? The only thing that appeals to me at all is the hacking the Gibson poster. Pretty cool. I have zero idea what all the other stuff is, if there are references I don't get them and the designs aren't interesting enough to intrigue me.
Maybe it's not my style so take my opinion with a pinch of salt. Hal9000 and Ono Sendai design are too basic tbh. Broseph feels much better. Also the black color really feel like it's for teenager or maybe metal vibe people (could be the customers you're targeting?). Maybe try to show different tshirt color in the front page so we know there is more than just black. Try to add more design? All the best!
