So, I'm joining a DnD campaign with a neato setting and decided to do a mockup of the game world.
As it's been explained to me, someone decided it'd be a great idea to shift a planet from one dimension to another without thought for what might already be there, resulting in both shattering against each other and the two cores merging, eventually forming a stable cloud of debris upon which life is, against most odds, still possible.
So, I drew this:

Problem is, I feel like it's missing something and can't figure out what. Was trying to go for the classic "space shading", which tends to be pretty binary, but I feel like in doing so I've made the debris field a bit sparse for what's supposed to be two planets-worth of matter despite not being able to fit much more in with any success.
Any ideas on how to fix this?
