Thanks- In Development

Thanks,
I am creating a piece for my brother; he helped me through some tough times, and as a gift, I made something based on an anime he loves. Demon Slayer. Using his face as a reference which is not here, Rengoku and Amine( A rapper). To develop something he could be excited about. What would it look like if he was in the anime series? I am still trying to figure it all out.
