Also you need to look at whats selling, not to copy but to get an idea of the style of shirt that sells on amazon. https://www.amazon.com/Spring-Break-T-Shirt-Colors-Matching/dp/B07PFZ1YML Have a look at this one. Yes its a loud, horrid, Leary shirt but it sells. I have a feeling your design will sit there for 90 days then disappear.

Don't take it personal dude, amazon is a funny old market to design for, it's almost like the cheesiest loudest shit sells, over high quality designs that take literally 10 times as long. research research research
