Change the oval frame to a horizontal rectangular frame with slightly rounded corners. Keep all existing artwork exactly as it is: the character, the swirling black ink energy, the kanji talisman strips, the seigaiha wave patterns, the Cyrillic text "САТОРУ ГОДЗЁ" at the bottom. Redistribute and extend the existing decoration to fill the new rectangular corners naturally, so no empty gaps remain. Keep the empty white oval space in the center untouched. Same black and white line art style, same line weight, pure white background, no shading, no gradients, no gray tones.
