Neat.
Nice song! The build up in the beginning of the song may have been a bit slow(for me), but the rest was pretty cool. About your info;
Your breakdown is absolutely fine. Anticlimax is good, but a burst out after the breakdown would've been nice too. Melody part WAS repetitive, but that's not necessarily a bad thing, now is it?=D Drums falling away was good, not too long.
The building down was good, very steady.
Hope this has been helpful for you Kriz.
