Piano sounds a bit "choppy" in my taste... A little more longevity on the notes would have been nice, or perhaps a longer reverb. It's mostly how the notes just end in wrong places. Also, have the same velocity on the same chord over and over again sounds very unnatural, which towards the end becomes a real issue, since there's no dynamic change inside each chord.
The guitar dies out too dramatically with that dive at the end; could have been a fade out or a bend in my opinion. I like the sound of the guitar though - it that feedback or an E-bow?
Not an amazing piece of composition by any stretch, but good for what it's meant to do :) Loops very well, and isn't too aggressive on the ear. Nice "shuffle"-ish beat. Overall, it's pretty okay :)
