The only thing i have a qualm about, and it may as well be a moot point, it sounds drowned out.
Now depending on whether you MEANT for this (to go along with the sound of the original game) or not matters very little to the overall composition I liked it regardless :P
Generally when I remake a song, I try to stay true to what the game provides. I have yet to really go all out and experiment with them yet, because I listen to the original, then I recreate the song in a format that can be edited by my software. So I would say it's somewhat on purpose, however as I get back into the spin of things, I might try something new.
Although, I can say I was trying a different form of instrument progression, just seeing how it worked.
Glad you liked it though.
