Welcome!
Great scan. I would suggest offering a lower poly version and baking those extra details in the normal/height textures. I dont see much from the description
- is it quad polygons only?
- do you offer different LOD versions? 1000 polygon, 3000 polygon, ultra high resolution (current polygon count)?
- is it PBR textures? Im curious did you do the material capture as well for the specular extraction, height extraction & pure albedo?
I think if you can cover these you will have a good workflow for photogrammetry capture to real-time models.
FYI I also sell some photogrammetry models and usually capture them in a diffuse/softbox environment. I have ordered some lights and polarising filters to do the material capture correctly for the next set and I think would be useful for future proofing your content. My 2cents.
