This started out as an experiment to test the limits of how many figures and props I could get into one render before the computer rebelled. This appears to be the limit. Hence the size and resolution of the final product.
It seems to me that the military would create units specifically tasked with superhero cooperation, were such characters real. So, I've indulged myself by combining four of my original characters (who've been taking up space in my head for years) with four better-known figures to illustrate the concept.
