I liked it !
I really liked a lot this music.
The biggest defect is doubtless the too big repetition of left. I had the impression to listen again to the music several times while it was not still ended in fact.
The beginning of the music is rather given rhythm, it is it's a pity that powers of the basses until the very present disappears suddenly to leave place has an a little less powerful beat. But well it is only a personal preference.
In any case I think that it would be necessary to avoid it stop and go. It breaks a little the rhythm and distorts the music.
Nice job ^^
