Dynamic lifestyle collage with dominant portrait subject

Create a hyper-realistic 8K dynamic collage centered on a dominant large-scale reference subject, male or female, preserving exact facial identity, facial structure, proportions, and natural features. Low-angle pose seated on a mountain top, legs slightly spread, right hand behind head, left hand on thigh, looking at camera. Red T-shirt, khaki cargo pants, black aviator sunglasses, black over-ear headphones, sharply cut out with a thick clean white sticker-like outline. Surround with layered smaller images of the same reference subject: jogging beside green trees in blue T-shirt/black athletic pants with backpack; indoor rock climbing in red T-shirt/khaki pants pointing upward; outdoor thumbs-up with dark shirt/backpack; desert rock formation in camouflage shirt; grey hoodie over red T-shirt with backpack in lush greenery; red T-shirt, black backpack and headphones looking forward; black leather jacket, grey T-shirt, black backpack and headphones smiling; ancient Greek temple ruins; distant indoor climbing scene with falling confetti. Cinematic lighting, vibrant natural colors, highly detailed textures, professional aspirational lifestyle aesthetic. 4:5 aspect ratio.
