The only thing I have found that dosnt look right is the fact that when you bomb a planet the shockwave dosnt follow the rotation of the planet, as soon as the bomb blows up it the explosion happens in that point of space, it would be nice juswt to see the dust or particles follow of the rotation and disperse. i think that might fix the fact that part of the explosion goes under the mesh of the planet and it looks like a half circle of particles flowing out.

And to make it even cooler they could add clouds and then move away as the explosion goes off

Just something to think about, ive only been playing for a couple of days and if someone aready said it sorry
