)This one was fairly easy. First I used mold a scene plaster to make a lunar surface. Using earth magnets, John Stewart is made to stand. I made Hal Jordan appear to fly by using coat hanger wire and the cap of a Bic pen. The prison construct for Sinestro I found instructions here at figurerealm. Simple glass jar and plastic spray painted with green transparent paint. Sinestro is standing on a small led light to give the piece a glow.
