Mood and lighting study in Unreal

The three pieces are created as a study for a one light setup in Unreal Engine. There is only one static directional light paired with a static skylight.

I was encountering issues when i was using regular HDR files as my sky material, but after some research i was able to create the sky material shown in the picture and by creating instances of it I was able to plug any sky that I wanted.
I am striving for photo-realism, so any feedback is always welcome.
