Very interesting concept. And it's very well done. You have no reason to be worried about this at all.
But it feels a little short to me. Maybe it's because I love those long, long stories with lots of action and B-plot and nasty villains and the heroes overcoming evil with extreme difficulty. And while I understand what Lois was driving at when she 'found' him, I wasn't aware that Clark (or Superman) had been lost, except to her. So I was a little confused until I read it over again (not that I minded).
But please don't take that as a negative, because it's not. It's my observation, not a judgement, and I agree that we should see more stuff from you in the near future. And I'd be surprised if it wasn't up to the standard you've set for yourself.
