This is my long-lasting project. I started creating it when there was no principled BSDF shader and now, after 2.79 release, I started working on it again. I improved materials and add some details. Post-proccesing is made in blender and Krita. All Textures from Poliigon.com. I hope you like it 
Have you also looked at using the Filmic tonemapping that is also in Blender 2.79?
It could really help with the blinding strip of light that dominates the image.
Yea, this is filmic 
I remember your project from start and this looks much better. Good job!
Well, I was not expecting that! Thank you very much
