It’s a high quality model work, supports low poly, created by cinema 4D. You can increase quality using subdivision surface. I usually export uv layouts of model and I put textures of models which have no problems into the same file. I’m trying yo develop myself in 3D projects also trying to give you my works controlling issues and fixing them. I’m trying to do best. Please feedback faulty works that I can help you. I will be happy when you rate and comment on my works.
