#4, 5, and 8....a bit too basic and unmemorable. I don't see a 20-30 year old male wearing a T-shirt with that logo on it like they would an Iron Maiden shirt or something similar. It doesn't stand out.
Thanks for the advice on replying to individuals, I didn't realize I could.
I think the design is just a bit too cartoonish. Unfortunately, everyone went more cartoonish than I originally wanted, but I'm out of time. It's cool, it's just not professional enough and, like I said, I don't see 20-40 year old males wearing these as a T-shirt.
