A playful 3D animated-style character illustration in a 1:1 square aspect ratio, recreating the composition from the reference image. A young boy with short dark hair and a serious expression stands with his arms crossed, wearing a light olive green button-down shirt and black pants. Next to him, a smiling young girl with long dark wavy hair tied in a high ponytail playfully pokes his cheek with her finger. She wears a sparkling light green sleeveless dress. The dark background is framed by vibrant glowing neon geometric light frames in bright pink and yellow, casting soft colorful highlights on the characters.
