Large scale aerial 3d environment


I’m working on a short film project which involves jet fighters and terrains.
Which software should I use for creating realistic aerial scenes (6-9kms above surface) ?
The scenes will have volumetric clouds and inworld light scattering, fog, haze, and a sunrise (as scene from high altitudes).
What software can give me the most realistic results desirable ?
I have been playing around with vue for about a week now and been able to get some good results but something surely seems off and I haven’t been able to pin point or go further from here.
I will attach a render for you guys to give me some pointers.
I am using 3ds max as my primary software for modelling/texturing/rig& animation.

Edit : New render
