Used HDRI on all. Never mind the changing scenery outside :D
Threw in a liiiittle volumetric on the sunset one. A bit too shallow of an angle on the sun to really see it though.

Thanks! :D The course really opened my eyes to the Histogram and False Colours. So nice to short circuit all that guess work I was doing previously. It is just so easy to go blind regarding how dark or light something is. Those damn eyes just want to adjust :D
