Hi spoky, long time no see. Happy New Year to you and yours.
I like the use of "color" or non-color as the case may be. My problem is making out the tan shape in the BG. I am thinking it must be like the eruption of a nuclear weapon? but it is very unclear. If that is the case, then I'm not sure the color choice helps define it. Overall, I think it's an interesting image, as all of your are.
