Cycles 4000s. Volumetric atmosphere. Blender only.
It is really good!
I mentioned somewhere else but even without post processing, if you turn the render contrast up (colour management and medium high or high contrast) you can immediately create more lively scenes 
I love the detail you put into the environment!
One suggestion I would make is to perhaps add some detail to the sky such as clouds or flying birds.
Couldn’t get more detail because insufficient memory in my PC 
I haven’t use volumetric clouds because it would decrease realism and increase render time significantly. And texture of clouds is not very realistic option too.
I featured you on BlenderNation, have a great weekend!
