not bad.
I've heard alot of zelda remixes, this one aint half bad. even though its a loop, you should try to make it a bit longer. I'm no expert musician or anything and I can't write how to improve it exactly, but you should continue this song, see what you can get it to.
who knows, mabey it'll be mind blowing after.
I'll give you 5/5 for interesting style, and 8/10 for the overall feel of the song.
PS: I don't really log in an review songs anymore unless they're really good.
