Mixed-Media Watercolor Male Portrait

Create an 8K ultra-high-resolution mixed-media portrait illustration of {argument name="character description" default="a handsome young South Asian man in his late 20s with olive skin, thick black wavy hair, expressive brown eyes, strong eyebrows, a straight nose, and a neatly trimmed full beard"}. Show him from the chest up in a three-quarter view, head slightly turned and gazing upward to the viewer’s right with a calm, thoughtful expression. Blend photorealistic facial rendering with expressive watercolor washes and architectural sketch techniques. He wears {argument name="shirt style" default="an open-collar patterned button-up shirt with geometric diamond and chevron motifs in brown, beige, black, and white"}. Use crisp realistic lighting on the face, detailed hair strands, natural skin texture, and subtle highlights, while the lower body and shoulders dissolve into layered watercolor textures. The background is clean white with vivid {argument name="accent color" default="cobalt blue"} watercolor blooms, ink splatters, soft gray washes, and fine architectural construction lines: vertical guide lines, diagonal drafting marks, intersecting grids, and delicate pencil-like sketch strokes. Composition should be vertical portrait, centered bust, high contrast between realistic face and abstract painted edges, elegant editorial style, no text, no logos, no frame, no extra people.
