Here’s an experimental cover I did back in 1989 for SWAMP THING #85. It was a western themed issue and SWAMP THING appeared for most of the story as an elemental energy storm. I tried to catch that by finger-painting the main image of SWAMPY as a titanic bolt of green lightning and stacking it over several color surprints to give it that crackling effect up the center.
