My personal take on the Orpheus looking back thing... it says that Orpheus has the tendency to lose faith which is why he looked back to check if Eurydice is still there because Eurydice is probably a shade by then so she doesn't have any footsteps or Orpheus being paranoid if he's leading someone else out of the underworld. Personally if I were Hades "Your music touched me so I let you do this ONE thing which is to not look back" and if Orpheus looked back, I might get offended because he thought I was tricking him when I gave him a single rule-breaking chance which is to bring the dead back to life. But I believe there's no words on how Hades reacted when he looked back, it's probably just underworld rules. And I'd be pissed too like Eurydice if because my partner struck such a huge deal only to mess up near the end and therefore trapped me in the underworld forever.
