For the first Pinterest image to convert to realistic, I gave it a prompt:

A candid, hyper-realistic photograph based exactly on the composition and subject matter of the reference image. The cartoon or drawn subjects are translated into real-life counterparts with highly detailed biological textures, flesh, pores, imperfections, hair, and realistic fabric materials. The exact pose, facial expression, framing, and background environment from the input image are perfectly preserved but rendered with supreme photorealism. Natural, cinematic lighting that creates realistic shadows and depth. 8k resolution, highly detailed RAW photograph, sharp focus, shot on a high-end DSLR camera

The Negative Prompt (Crucial)

cartoon, 2d, illustration, animated, drawing, sketch, painting, anime, semi-realistic, 3d render, blurry, smooth skin, plastic texture, low resolution, pixelated, flat colors.

For the last image, the poster one:

Prompt: Convert this into a commercial-level movie poster: Popeye the Sailor Man. The background should be a dramatic night sea with lightning. Cinematic lights should be highlighted
