I'm pretty dumbfounded by how amazing this is. I listened to it a few weeks ago and I'm listening again now.
On the second listen I noticed that I think it would be better if your consonants were softer. It sounds like you have a voice teacher who's constantly telling you to enunciate with very crisp consonants, but this is one case where it seems like you're hitting those consonants too hard, especially t's and p's. This song is a lullaby and it should sound sleepy. The t's should sound a little like d's, the p's should sound a little like b's, etc. It would sound more natural and would flow more smoothly that way.
As I continue to listen I'm noticing parts where the consonants do sound softer, so I guess you're already halfway there. The last sleep at the very end is very soft of course.
