Pretty good, but...
FAR too repetitive. I like the guitar, it's well-made, but...
(a) Too repetitive.
(b) Not much of a beginning.
(c) No real end.
Genre-specific issue(s):
FAR too strong drumline.
FAR too quick pace.
It's a good song. I don't think it should be ambient though, I'd put it under misc.
9/10 for song overall, -2 for the errors, -1 for the length.
