I try it in hard mode ;). Part one is linked with part five. Part two is linked with part three (happy life). And part 4 is special it's a break with the other parts and a climax.

0-55'' : Wild nature.

55"-2.29" : Pastoral state 

2.29"-3.29" : The consummation 

3.29"-4.20" : War, destruction, fear

4.20"-END : Desolation - The cycle can restart (I used the same harmonic Violon I used at the very beginning of the track.

I hope you'll like the track I spent time on it.
