Short film and Aurora B look dev

Currently working on a short film project, two effects needs to be lookdev'ed- "snow" and "northern lights". Been working on the latter, here's the animation pass. I believe I get enough niceness from this approach of simulating realistically rather then some kind of motion graphic trick solution which would be cheaper but not as fluid in it's movements.
It's interesting that I haven't seen anywhere where they succeed with this thing. Maby because all cool script writer lives too far from where the auroras is happening.
