Tarjeta Postal Infantil Realista - Prompt Fotográfico

A realistic photograph of a children's postcard placed on a wooden table, viewed from a slight top-down angle. The postcard is in landscape orientation, made of lightly textured off-white cardstock. It is handwritten in blue ink with naive, uneven, childlike handwriting. On the left half of the postcard, include the following placeholder text block: [POSTCARD_TEXT] Below the text, leave space for a crayon-style drawing as: [DRAWING] On the right side of the postcard, include lines for the recipient's name and address, and in the top right corner, a nature-themed postage stamp (e.g. mountains or trees). Ensure the image has realistic lighting, shadows, slight depth, and natural imperfections to create a convincing 3D photographic look.
