Ok first.. I LOVE THIS! And second I swear I didn't steal the name Olive from you Lol.. Um I don't really think the story was rushed I enjoyed it being a bit quick but it filled me in on the story so it wasn't just jumping all over the place (Which I enjoyed). I really enjoyed this storyyy!

You know, i like it.
I always love interesting concepts and plots, especially with fantasies.
It's amazing what the mind can come up with.
Anyways, I did feel like it was a little bit rushed, maybe you could spend some time earlier defining some of the characteristics of a cloud walker and what they do and such. And I know that not revealing things until later is a very fun thing to do when writing, but sometimes it just leaves others confused.
Overall, it's a very nice story, and it has a lot of potential!
Keep Writing! From one author to another.
