Well, the two moons were meant to form the eyes of a face in the sky, the massive personification of terror/fear/anxiety, that's the whole concept of this piece, hence the title; the trees and ufos are really just a by-product of that, they were meant to act as sloping "eyelids" for the moons to reflect the same anxious expression as the running character. I guess that wasn't executed well and was confusing, so I've changed it around a bit now and ditched the concept altogether:
I plan to draw the branches of the trees in the foreground with the same "fading out" lighting as the new tree, I just haven't got round to it yet. I have to fix the palette too. I'm thinking of putting a few multi-coloured illuminous objects around the rest of the trees in the background. Alex, I'll remember to put in highlights on the tree tops from the moonlight, thanks for reminding me.
