I know it can be improved. There's a strange patch of color near the caldera, and the frontal area has white spots, probably due to interference of clouds and displacement intersection or something. And the clouds should be more billowy in the lower area, but I need to find the right settings for that. I can also use more cloud layers, instead of just two (in the spume). I can add debris and rock being thrown out, etc. All possible (in my head), now find the time...
