Wow, I mean, this is really good.
You had me smiling through two whole loops easily, and even though it doesn't loop perfectly I didn't notice the separation between the first two loops I listened to (was distracted checking the comments). I don't really notice the transition between loops unless I'm listening for it.
The song is already entrenched in my brain, so it all sounds good to me now, but there is one complaint I had on my first listen. The note transitions of the synth carrying the melody (is it called a pad?) felt a bit slow and clunky, same with the bass. Now that I've listened to it many times I know when to expect the note to change, so I don't notice the clunkiness that I felt on my first listen, but it did affect my first impression so it might be something to think about.
But really I can't think of anything else to criticize, you've done a fantastic job with this piece and I hope to hear more from you soon!
