Edición de Luz de Borde Dramática

put a subtle but visible blue rim light around the muscular shirtless man character on the left punching, and a subtle but visible red rim light around the large brown muscular spherical creature character on the right. Darken the background significantly including the prison-like corridor and suited men so that the characters and rim lights stand out prominently. Do not change anything about the characters, the way they look, their poses, positioning, or any details. Preserve exact anime-style illustration, high resolution, sharp focus, dramatic lighting with rim lights, professional quality, rule of thirds composition.
