Create four separate ultra-detailed funny caricature portraits in the same artistic style, featuring Neymar Jr, Kobe Bryant, Brad Pitt, and Roger Federer. Each character should have exaggerated facial expressions, oversized head proportions, playful smirks, funny crossed eyes or cheeky expressions, and confident poses unique to their personality. Style should combine realistic facial texture with sketch-art, watercolor, ink splatter, pencil strokes, and painterly detailing on a warm beige textured background. Keep the portraits highly expressive, humorous, and premium-looking with dramatic lighting and sharp details. Neymar Jr: wearing Brazil or PSG jersey, tattoos visible, stylish haircut, playful confident pose pointing at himself. Kobe Bryant: wearing Lakers jersey #24, funny smug expression, confident basketball legend energy. Brad Pitt: elegant tuxedo look with finger-point pose, charming mischievous expression, Hollywood charisma. Roger Federer: wearing classy white tennis outfit and headband, subtle funny smirk, relaxed champion vibe. Art style: exaggerated caricature realism, editorial sketch illustration, watercolor + ink hybrid, ultra detailed, expressive face anatomy, textured brush strokes, dynamic line art, premium digital painting, humorous celebrity portrait series.
