A 10-year-old boy and girl of different races with joyful expressions are sitting at a table eating Halloween cookies. The cookies are shaped like pumpkins, witches, Frankenstein, ghosts and bats, and are arranged on a plate decorated with Halloween motifs. Both children are wearing Harry Potter-type wizard costumes, with black robes, Gryffindor scarves and round glasses. The image has a 2:3 ratio. The scene is lit with natural light, highlighting the details of the costumes, the cookies and the children's expressions. The image should be photorealistic and should not have flaws such as deformed hands, disproportionate arms, extra fingers, fused limbs, misaligned eyes, vacant stares, misshapen eyes or unequal pupils.
