Wow! Very cool.
I’m sure the YouTuber, Jazza, might love this. He used to paint Warhammer figures on his spare time before he became an art YouTuber. He even has done a few YouTube videos where he makes a custom Warhammer figure. The old backdrop for his studio also used to have a warhammer character on the mural. If you want, you could share your artwork on Jazza’s official Reddit page. If you’re lucky, Jazza might comment on it.
