Designer for my merch

I'm looking for someone to help me make a shirt for my merch. It's going to be a t-shirt made from cotton fabric. I don't have a time limit for this project, so if you need more time to get the product just right that's fine. I'm open to your ideas - if you think this design could benefit from certain changes, let me know. I'm excited to see what you come up with! The cross is the back, and the other side is the front.
