Nice song, bro!
You deserves feature!
But let's talk about music.
The chord choose is very nice but at 4:11 one chord disturbs me. Talking about the end, the end feels like... another song. Like you take one song and put it into end of this song. But this doesn't matter.
I love melody anywhere in the song. But the best is around 1:15.
Good luck and hope you will make new songs soon!
