Creation of the Outdoorlevel with future plans

The feeling I want the player to have: 

I want the player to have a sense of awe when playing this level, partly from the size but also from the way the world looks. I also want to add elements that make the world feel similar to our own but with slight differences, taking the player into a different world experience. 

The Future:

• I want to add the stone henge to the world
• Add water
• Change grass in the river to dirt or sand 
• change the hills into rock, going for a red rock but if I can't find a good red rock texture normal rock
