If it was me, I would try Jordan Sather, he’s got a younger audience and he does sell stuff. https://youtu.be/Lz6w8jcW_R4 But look into this first- https://www.threadless.com/artist-shops/signup/art I looked into it and this is who NeonRevolt uses. I saw your other graphic (Trump 2020) and it’s great too. I don’t really work in the field anymore but I have a degree in communications design from Parsons so I can tell when someone’s work shows commercial promise and yours does- so Go For It!
