My philosophy is not asking if my models will sell, but to make searches to see what is selling, therefore applying your likes, skills and talent into that topic, theme or subject.
I had recognize 4 customer profiles so far:
1. 3d printed models for DIY/ printing enthusiasts.
2. Props and objects for Social games (SL, IMVU, SIMS)
3. Iconic daily objects for interior, renderings, digital content.
4. Detailed Objects for VR, product retail and promotions.
If you wanna chat a bit more later, dm me.
I hope this helps a bit
Regards
Arturo
