I also tried that on Gemini, and while it does a decent (but not ChatGPT level) job of generating Liberace and the troll, it makes the baby as a baby. Curious, I uploaded the above image and asked Gemini to describe it in detail, and got this:
Summary
This image is a close-up, portrait-style composition featuring three figures: a man who bears a resemblance to Liberace, a creature that appears to be a troll, and a swaddled baby.
The man on the left, with dark, styled hair, is wearing a white jacket with an elaborate, possibly textured or embroidered pattern, over a white shirt with a ruffled front and a white bow tie. He is looking down and to his right with a warm, closed-mouth smile, cradling the swaddled baby in his arms, with his hands visible supporting the infant.
Standing closely behind and to the right of the man is a creature resembling a troll. It has greenish-toned, wrinkled skin, large ears, and dark, somewhat wild hair. The troll is also looking down towards the baby with its eyes partially closed and what appears to be a gentle smile, its face positioned close to the man’s head.
Cradled securely in the man’s arms is a baby tightly wrapped in a plain white blanket. The baby’s face, with its eyes closed, has features and light-colored hair that resemble those of a known public figure. The overall expression on the baby’s face is serene, suggesting sleep.
The lighting in the image is soft and warm, highlighting the faces of the figures and creating an intimate atmosphere. The background is blurred and indistinct, keeping the focus squarely on the unusual trio. The image has a high level of detail, suggesting it is either a photograph or a highly realistic digital rendering.
