Show HN: Facemodel, create 3D models of your head from a selfie

The reason you'd give somebody a free demo is so you can show what the product does.
I get that it is GPU intensive, and therefore cost prohibitive if you got lots of traction, but as you have it now, you haven't provided enough proof of what you've done here.
So, if you don't want to offer people the ability to upload and create their own 3D model, how about a video showing it being done, a few samples that are more than just a single photo of a face which is then applied to what looks like a fairly generic head.
I don't have anything to view your model file with. Can you make a webviewer, or at least a video showing you rotating the model or SOMETHING.
Also, you say $5/month but what would I do with that subscription? How many models am I going to create from a selfie? Why would I do that?
Though a web-viewer is great, even just a video capture showing you moving around a model would be a good start.
If nothing else, put something to read on the site. This is selling an identity projecting product. The non-technologists it will attract will be people wanting to act out imagined realities with their identity. Simply descriptive prose of this giving customers the ability to be themselves and bring their friends, realistically, into other realities is a huge selling point. Use it.
Best of luck.
Get lost.
