The hair on the corpse is red but it's unclear if that is a result of mummification iirc.
Egyptian dynasties came from all over the shop at various points, 3 millenial is an insane amount of time. And Egypt was the cultural and political hub for a long time but as you say Rameses probs didn't look like this. Kinda weird of them to do this.
I have no idea who can afford this shit atm.
Also please fuck off with forever culture. Things can be in the past. It's ok to move on.
