Middle Of Nowhere

First big scene done in Unreal Engine 4.
Practicing everything from texturing, creating UV's, using unreal for renders and creating lighting. The switch from Unity to Unreal was great. Last time I attempt was back in the days of UDK...
The biggest issue I had was when it came to building my lighting my shadows would just look like blobs. So any tips would be much appreciated!
I came across this concept on Artstation and couldn't help my self. I really liked it. Did a few changes to it but happy with the results.
this concept came from https://www.artstation.com/artwork/BW3wz

Revisions coming soon!
