I really like how you have built the picture, the entire idea seems to be going upward with the civilization finish on the top! It's like a transition of the entire story of earth:

1. The sea and the primal element of water
2. Land and the lush tropical forest
3. Mountain and the steep edge
4. Ancient civilization and the ruins of time
5. Modern civilization growing on top of history, based on it yet entirely new.
   I don't really know if you have seen it that way, but you did a great job.
