Thanks for the tips! Is there another version on someone else's thread? The only one that I saw was 4-D's arrangement from 2009 (after running a search). I had assumed that this song was open for the taking.
-They're not triplets? That
is shocking. I could have sworn that they were.

-I'm not good with chords. From what I can tell, the chord that plays is beyond human playability, so I tried to reduce it to playable level. Apparently that didn't go too well.

-True, I'll remove the marking. Would "con pedale" work instead?
-I'm not sure how to accurately portray that chord in measure 5. In the original song, it crescendos from almost nothing to its normal volume, but I'm not sure how that would work with a piano. Would playing it as a half note work instead?
-Would it be better to have the left hand cross over the right hand to play those chords at the end? To be clear, I mean leave the right hand exactly as it is, raise the left hand 2 octaves, place it in the treble cleft, and note that the left hand crosses over the right? Or would it be easier for the right hand to play the chords, and the left hand to take the right hand's part?
-I'll also fill the chords in a bit more.
I'll work on it this afternoon; I have to go to class now.
