Make this prompt your own

Who is in it: “A smiling boy holding up a bright blue 3D printed prosthetic hand gripping a ball” is the part that describes the people. Rewrite it for someone else and leave the other words alone to keep this look.
Light: The prompt does not ask for a particular light, and the picture came out with soft daylight. To steer it, add a few words at the end, such as “daylight” or “evening light”.
Rules: It ends with “No text”, so the tool adds no letters or signs. Leave that in and add your own words later in any editor.

Same theme, another look

In other light: Cozy Night Desk Setup (warm lamp at night), Paying by Phone QR (bright daylight) and Virtual Reality (neon light).

In another style: Drone Over Farms (tech photography), Robot and Human Hands (tech concept) and Circuit Board Brain (concept art).
