This composition reminds me a lot of Johann Sebastian Bach's 'Ave Maria' melodically! I can't figure out if the (I assume) feedback from the reverb is satisfying or distracting. It's certainly interesting and it's not unpleasant, and I like the way it spreads across the sonic field, but when there's a lot going on, it can become a bit distracting. The drum also seems a bit out of place and doesn't necessarily fit rhythmically. It could do with being quantised so that it fits exactly to the beat, which I think might improve it.

Overall, this song has a very relaxed and ambient feel and could be a 5 star with a few tweaks!
