I'm a recent mechanical engineering graduate and now a full time artist. I have always loved fantasy, and last year I learned how to 3D model.
The majority of my models consist of Patreon requests and commission work.
I really love doing Patreon requests because it is a happy medium between being motivated to complete models while having artistic freedom. You can submit your own request at www.patreon.com/m3dm.
I sell improved versions of my models, and share the rest for free. The key improvement is a decorative base to tie the model together. If I ever update the files with improved design either for detail or print-ability, I update the improved versions.
