Create a vertical anime-style watercolor portrait of Nikke standing outdoors beneath a vivid summer sky. Show a close-up three-quarter side view from the chest up, with the character facing left and gently holding a single pink-and-white silk tree blossom near her face. She has deep indigo blue hair with violet highlights, long bangs, and a high ponytail flowing to the right; add a gold hair clip reading “AI” near the temple and multiple small ear piercings. Her face is mostly covered by a large centered opaque square overlay with a muted blue-to-dusty-pink vertical gradient, concealing the eyes, nose, and mouth. Dress her in a sleeveless high-neck teal blue top with soft painterly shadows. Surround her with exactly three prominent silk tree flower clusters: one small flower held in her left hand beside her cheek, one large blurred foreground cluster at the bottom right, and one flowering branch cluster in the upper right corner with green leaves. Use a slightly faded but powerful blue palette, cool white balance, humid summer atmosphere, increased green tones in the shadows, strong visible film grain, watercolor paper texture, expressive brush strokes, bright backlighting, soft cloud patches, and sparkling highlights. Composition should be intimate and poetic, portrait orientation 9:16, with no extra text except the “AI” hair clip.
