I made the shirt design for my OC, Jasmine “Jazz” Harper, into a proper render. It’s a simple design, meant for easy reproduction. I also made a version that enhanced it with a brass frame.
I added the simple design to Redbubble here: https://www.redbubble.com/people/sada-tainment/works/39246360-volume-bars-simple?asc=u
And the brass iteration is on Redbubble here: https://www.redbubble.com/people/sada-tainment/works/39246362-volume-bars-brass?asc=u
