Special effects are fairly easy (and positively required) in comics. This is our gal Valkris in action against an archmage. As an art study, it shows the importance of contrast, color harmony, composition, and use of dead space. On the left, the background has little detail but an ominous feel; so does the deep plum color on the right. Reflected light is key in picking figures out of dark surroundings. Just for curiosity, the spell is a black hole type, and the mage is sucked in along with trees and a ton of dirt. A guy has to know his limitations.
