Circus Above Cumulus
Pure entry. Cycles 256 samples, procedural textures, compositor.
Please pardon the lazy marshmallow clouds and the giant inverted chocolate pudding. 
Some earlier ideas are Manfred von Richthofen’s flying circus of WW I (but I don’t favor biplane/triplane too much) and circus tent on a ship/boat (but then the airship/dirigible idea popped up and here we are). Was struggling with what should be under the tent, also don’t want to do much volumetrics for the clouds, and so the choco pudding (lifted ground/soil) and marshmallow clouds were born. Not too proud of it, btw.
