Hi.
My name is Niven. I am a solo indie game developer. I work with Copper Cube 6 game engine, pretty decent one, but not the best. In short, I found your page on Sketchfab and some of the designs are just amazing. I would love to get a chance to download one of those and if you are available to negotiate for a price or a simple credit, I will be down for that.
I humbly ask for your help and once again, if we can contact each other that would be great. Best to you.
