Hey Colin,
I'm kind of lost because I'm not into rap at all. So I can't comment on the style and what's good or not.
Thing is, I like your voice on the lower notes when you get out of falsetto.
Maybe you can go for songs that utilise more of your lower tones...
Just saying ;)

I agree. Sometimes it hurts just listening to my voice. When it feels good it sounds good.
Good call PC

I love the soft, unassuming vibe of this track. Kind of a Destroyer meets Flaming Lips vibe. The rap vocal sounds a bit soft. The singing vocal is a bit pitchy at times, sometimes struggling on those high notes - but not terrible by any means. The vocals have nice honest simplicity that really does compliment the instrumental. I would just suggest a slight boost in the vocal mix and fix some of those pitchy moments.
