Use the photo I've attached of my pet, a {{pet_type}}. Create a photo of my pet dressed as {{costume_idea}}, sitting on our front step on Halloween night. Keep my pet's breed, size, markings, fur color and texture, eye color and expression exactly as in the photo. The costume looks like a real, well-made pet costume sized for my pet: soft fabric, nothing covering the eyes, nose or mouth, ears free, and no tight straps. The scene: blue hour, a warm porch light above, two glowing jack-o'-lanterns, a trick-or-treat bucket and a few fallen leaves on the step. Camera low at my pet's eye level, 50mm lens, shallow depth of field, a catchlight in each eye, and the pumpkins' glow warming the fur. Palette of deep blue dusk, pumpkin orange and porch-light gold. Let my pet look proud, curious or a little unimpressed, whichever fits its face in the photo. No text, logos or watermarks. Format: {{aspect_ratio}}.
