My feeling is that you need to let users choose the demographic rating their photos.

This clearly has a bit of a cold start issue though.

I'd really love for a service using ELO/relative ranking to exist and exactly for this purpose.

I've used https://www.photofeeler.com in the past - I think you're looking to give users a similar service. I have greater faith in your ELO method though.

Perhaps to give you some motivation, I've paid over $50 for that service to get a feel for different profile pictures. I'll continue to use it too as I consider new photos.

They have a slightly clickbaity blog, but it has some interesting posts like this one: https://blog.photofeeler.com/psychology-study-science-best-p...

Thanks for sharing! I've seen Photofeeler.com around.

Have not added ELO based rankings, but might be fun to implement this in future.

What and how do you think I should change for in Facerank?

I think being able to say, "only allow women/men aged x to y to rate my photo" would be the main one.
