Not bad ;) I haven't read many fics (yet) but I do like the various descriptions used throughout.
I found one small mistake though (minor)
"I'm gonna be fine mom, and you will too. I'll call you whenever I can, and you can whenever you need something!"
And please don't take this in the wrong way, as you are new here (heck I'm still learning stuff, especially in the fic area), but the beginning journey thing might be a bit "cliche". Perhaps more experienced writers here may comment on it. Though I sympathize, because I'm guilty of intending to write something cliche-ish as well (which I am still trying to iron out, I'm too concened in even just posting my premise/prologue). I realize too that its probably something you want to get off your chest so to speak (after all imagination ftw). However considering how well it was written, it's definitely a good start. :)
Theres some good guides around here too that talk about how to make a good fic, they're definitley a good read. :)
