Transform the young boy in the middle into a much larger, extremely muscular adult man. Make him significantly bigger and more muscular than both women on either side. Give him massive, defined muscles like a bodybuilder - huge biceps, broad shoulders, powerful chest, and muscular arms that are much larger than the women's. Keep his position in the center but make his physique dominant and impressive compared to the muscular women. Maintain the same clothing style but on his now much larger, adult frame.
