Hi!
I visited your profile and took a look at your models. I noticed that you currently have only two models uploaded, which is quite limited. Also, the preview images don’t present the models in the best way
they lack visual appeal, which might discourage potential buyers.
Another point is the pricing: it's relatively high compared to the quality offered. Honestly, I could find a similar model at a lower price and sometimes with better presentation.
My advice would be to focus on building a larger portfolio with high-quality models. Upload multiple clear renders from different angles, including wireframes and UV maps. Also, consider lowering the price a bit in the beginning to attract your first customers. Most importantly, make sure your main thumbnail is the best render you can produce — it’s the first thing that catches a buyer’s eye
