Childlike crayon-style family camping drawing

Keep all other elements in the image exactly as they are, and change only the drawing on the sheet of paper to a different style. The content of the drawing is a camping trip taken with a {argument name="vehicle_en" default="caravan"}. On the left, the two people are {argument name="left_characters_en" default="a mother and child"} sitting at a table, and on the right is {argument name="right_character_en" default="the father"} grilling meat using a {argument name="cooking_tool_en" default="barbecue grill"}. Change the drawing into a style like an elementary school student’s crayon drawing.
