Remove the woman in the white cap on the left side of the path, along with her whole body, the part of the leash connected to her, and the shadow under her feet. Fill that area with matching path, grass, fallen leaves, and park background so everything blends in naturally.
Delete the woman wearing the white cap who is standing on the left side of the walkway. Make sure to remove her entire body, the section of leash she's holding, and the shadow beneath her feet. Replace that whole area with more of the same path surface, grass, scattered leaves, and park scenery so it looks like she was never there.
