Extend this exact image to a vertical 9:16 frame. Keep the existing picture completely unchanged: the same woman seen from behind eating chocolate cake with a fork, the same pink worm coiled around her with its eyes and hooked mouth on her shoulder, the same colors, light, sweater, table, cake and macarons. Only add more of the cozy café scene above and below so the whole original content, including the cake on the table, fits inside the vertical frame. The woman has only her own two hands, no other people or hands. Photorealistic, no text, no watermark.
