I'm trusting my gut instinct on this one, and it's saying that some of these lyrics feel a little off in one way or another. Namely:
-"but the ticket that you're holding, it only goes one way" (to me it sounds awkward and forced)
-"one going up to heaven, the other one down to hell" (I can't imagine a good flow for these lyrics)
-Entire chorus (same reason as #1)
But other than those three areas I just can't get into, the rest is good. I can't really conjure any replacement lyrics, but just giving my opinion and letting you know that some of the lyrics aren't really clicking with me. Good job on the rest, though.
