You've brilliantly succeeded the challenge (thanks for posting the chords). The music and melody remain consistent throughout, despite the changes in harmony.
You didn't need to modulate, which is great.
The mood is very nice.
But I'm going to reiterate some things that have been said in previous comments: why the white noise? And also, the attack of a synth is very short and causes a little click from 1'22".
Otherwise, it's really great.
