I enjoyed it.
To be honest when it first started I didn't think it was going to be good, but I kept listening anyway. I am glad that I did. It is a really nice mellow track, very moody. There's not too much going on, which keeps the focus more on the feeling behind it. I think I listened to it about 3 or 4 times writing this review.
(p.s even my puppy seemed to like it. She was going crazy then I started listening to this and she seemed to calm down and came and sat on my lap and is just laying down now!)
Liked it a lot, especially the choir and the piano-ish pattern
But I think you should make it shorter to like 3 min
Or, if you want to go straight to the newgrounds top 10 (and maybey even the real life charts), you should find a guy/girl who can sing awesomely good and put vocals on it. If you do that (and I really think you should) you will absolutely have an amazing song, belive me
Btw, I'm sorry to hear about your grandma, I know who you're feeling at the moment, and it's not a real nice feeling
