Using the attached approved character image as the identity reference, create a pixel-art walk-cycle concept sheet of the same fictional adult character. Arrange exactly four frames in a single horizontal row, each occupying an equal cell: contact pose, passing pose, opposite contact pose, opposite passing pose. The character faces right in every frame. Preserve the same outfit, colors, hairstyle, proportions and pixel scale. Align the ground contact baseline and keep every frame fully inside its cell with consistent padding. Use crisp square pixels, a limited palette and a flat solid warm off-white background. No text, frame numbers, grid lines, motion blur, extra characters or watermark.
