A medium shot captures a feminine

A medium shot captures a feminine male character, a femboy, standing with one hand on his hip while holding a spear in the other, posed dynamically from a three-quarter front view. He has long, flowing blue hair cascading past his shoulders, framing his delicate face with a confident, playful expression, his blue eyes looking directly at the viewer. His slim, androgynous build is dressed in a form-fitting sailor uniform: a white short-sleeved top with a blue sailor collar and red neckerchief, paired with a pleated blue skirt that accentuates his hips; his left hand rests on his hip with fingers splayed, while his right hand grips the shaft of a tall silver spear angled across his body. A distinctive blue shark tail sways behind him. The background is a simple gradient sky in soft blues.
