Great work
There are alot of elements that I really enjoyed. It is a very subtle song with some good harmonic keys and some dark undertones. there are a few flaws that I heard, though they were minor. There are some moments were the sound clips out I think it's around the 35 second area it is something is recurring throughout the song. More likely happened when you switched your sounds on the keyboard. I might not have noticed it had I been listening to it through my speaker. ( good pair of headphones make music more enjoyable.) Other than sound clipping you fantastic job on the arrangement, so for that I give you an 8. Keep it up!
