Draw a chalk adventure around my feet

Use my uploaded user photo with visible pavement or floor. Freeze the subject's body, shoes, face, pose and original shadows. Draw an anamorphic chalk [ADVENTURE SCENE] only on the ground, aligned with the camera's vanishing point so it reads as a playful illusion from this viewpoint. Let the original shoe shadows fall across the chalk naturally; preserve real cracks and stains beneath the pigment. Output one composite and a note describing the correct viewing angle. Do not add a fake real-world hazard, change the street markings or place chalk across another person's body. Compare shoes, shadows and road markings with the source before accepting the chalk illusion.
