I agree with all of this. It sounds like he tries the gruffy / scratchy voice too hard and it falls apart. There is some good build up in the song but it doesn't pay off.
i loved his super high voice back on the Emarosa EP. But he was 16 or something so I guess he hadn't hit puberty at that time yet. I also liked his cleans and screams on Agraceful. I don't so much like his vocals anymore but I'll stick with it. He still has some good moments
