It’s a nice track, and if I didn’t know it was yours I would have guessed it anyway. That’s a good thing in my book, I still fondly listen to heartstrings every now and then 
The others have said it, but I too find the drummachine-style drums not great for the track, the snare and especially the toms I would consider replacing with different samples. It’s a nice song though, you’ve got a great feel for layers. You manage to stack many different melodic elements without overcrowding the song.
