The song in general is good. The background drone(?) fits well with it and gives it a nice ambient feel, which seems to be what you were aiming for here. Also, that part at 0:32 with the drums(?) was one of my favorites. However, I do have a few problems. The section at 0:16 was pretty annoying, repetitive, and didn't fit well with the song. Also, the song itself is similarly repetitive.
SUGGESTIONS:
I know this is a section from another song you made, however it could definitely use some variation. Maybe try adding in some extra notes? Also, 0:16 would be better if it wasn't as repetitive. You should either shorten or change it.
