I was wondering if anyone had tried it with others. Having good quality pictures makes a huge difference!
I know of a person that restores and colourizes old photos, and the results are seriously amazing. He did Billy the Kid from that old tintype and I was absolutely stunned. This link is from Instagram so I hope it works:

I don't think it's overly expensive, I'll try and get Ringo done then re-animate him.
