Any tips on the lighting?
I'mma be honest for your piece, and not just in general.
The lighting is all outta wack.
There is no way those clouds in the background can be
that orange without the sun also lighting up the man in an extreme orange hue.
The green glowing man's glow is pretty bad, it's way too big to not have bloom, and not small enough to be ambient.
The buildings in the background are almost pure black which looks hella outta place. They should be getting sunlight too.
The lamps look to still be on, so they should be emitting light on the floor
that's visible. Use volumetrics.
The fog in the background ruins a lot of the picture, so you should definitely get rid of that. Also add some orange smoke particles to match the dust in the background.
The main subject just looks tiny and huge at the same time, way bigger than the lampost, but small compared to the body lying in the ground next to him.
Move the camera closer and lower the FoV.
