I like this track. At first it doesn't really sit well, but it grows quickly, which is good with a loop. It definitely strikes me as a dark forest-y kind of theme, which is also good. So All-in-All, this loop doesn't really have any problems. However, I think that if at the end you kept the flute-thing going every 4th note, instead of cutting it behind the chords, I personally would like it more.
Please contact me if you would like to use this in a project. We can discuss the details.
