The pads and the piano transcribe well the space aspect and the whole beginning is really good.
The pad and the piano answer each other in harmony and then in dissonance before coming back in harmony again.
There is a grandiose and worrying side.
But from 38" on, the piano dissociates from the pad and only disharmony remains. I find this part less good. You could have probably benefited from putting the instruments on the same key at the end to soften the tension.
