Two brothers standing side by side but facing away from each other

Two brothers standing side by side but facing away from each other, clearly angry. One brother is a muscular bodybuilder with a strong, defined physique, while the other is noticeably skinny and slender. Their expressions show frustration and tension, with furrowed brows and clenched jaws. The background is simple, perhaps a plain wall or a neutral setting, to keep the focus on their contrasting body types and the emotional intensity of their disagreement. The scene should convey a sense of conflict and the stark contrast between the brothers.
