Create a whimsical watercolor and expressive ink sketch portrait in the exact artistic style of the reference image. Use the uploaded image as the strict identity and outfit reference, faithfully preserving the person's facial features, expression, hairstyle, skin tone, clothing, accessories, and overall appearance. Do not redesign or replace the outfit—keep the clothing exactly as shown in the uploaded image. Maintain the loose painterly watercolor brushwork, expressive flowing ink scribbles, airy cream-colored background, wild grass, tiny flowers, and delicate butterflies from the reference style. Add the word "Yuuna" elegantly in the background as refined handwritten calligraphy that naturally blends into the artwork rather than appearing as a separate text element. Preserve the soft earthy color palette, minimalist composition, abundant negative space, and dreamy, emotional fine-art illustration aesthetic. The final image should feel like a hand-painted watercolor and ink sketch while clearly retaining the identity and clothing of the person from the uploaded image.
