Alien Landscape Color Study part 1

We have to make an landscape focusing on unrealistic colors and their tones for the dark areas and opposite colors contrasting each other. I'm the only one in the class so far with an unrealistic landscape. I tried to make brown-green spires with bright yellow highlights, and a contrasting blackish-blue purple sludge next to it. I'm hoping to throw a monster skeleton into the sludge, floating island with castle or space-age skyscrapers... which would contrast with the apocalyptic feel of the landscape, yes i think i'll do that... and a moon and few planets with the milky way in the sky.
