A male superhero with a fitness body stands confidently, wearing a sleek, streamlined Rocketeer-inspired outfit without any symbols. His helmet is reminiscent of the iconic Rocketeer design, and his face is meticulously detailed with striking eyes that convey determination. The full-body portrait captures him in sharp focus, with no blur, showcasing hyperdetailed intricacy and the finesse of 8k resolution concept art. The scene is illuminated with cinematic lighting that emphasizes triadic colors, creating a dynamic and visually engaging atmosphere. Taking cues from the artistry of Greg Rutkowski, Artgerm, WLOP, and the elegance of Alphonse Mucha, this splash art echoes a modern trend on Artstation, blending realism with an idealistic vision of heroism.
