Mockup Koszulki z Rysunkiem Yuru-Kyara

A white t-shirt product mockup shown in a flat lay, front view against a plain white background. The graphic print on the shirt features only black line art with no color fill and no shading. The illustration style is hand-drawn with soft pencil or crayon texture, with slightly wobbly, uneven lines, varied stroke pressure, and open outlines creating a charming, childlike doodle aesthetic with no vector precision. Printed graphic layout: - Top center: Festival logo reproduced exactly as shown in the reference photo, retaining its original typography and clean graphic style without hand-drawn distortion. - Top right: Hand-drawn spiky, explosive manga speech bubble containing clumsy hand-lettered text reading "[Insert dialogue here]". - Middle: A simplified, loose yuru-kyara style sketch of the character from the reference photo, occupying no more than 40% of the shirt height with generous negative space. - Bottom: The artist name "[Insert artist name here]" written in shaky, uneven hand-lettered pencil script. Clean, balanced spacing, minimal composition, no background props.
