Very good.
I can picture so many different places this song could work great in. Walking on a beach on a clear full moon night, walking in a forest at the break of morning, the possiblities to me are endless.
The song itself was very well put together. Never got boring to listen to and I also loved how you made it build up for a good while, then you let it die out near the end of it. The song length was perfect and it's a song I could listn to over and over again. Excellent work and looking forward to more songs from you.
