Holy. Frakkin'. Carp.
To be honest, when I heard this I thought you had simply copied the symphony version of it. After listening to it, I realized this was actually better in some ways. This is pretty much my favorite game song. It and the Cosmo Canyon theme are pretty much the most emotional pieces in the Final Fantasy line, in my opinion.
Very well done, and thank you for making an already elegant composition even more so.
