Honestly, really disappointing, especially since the author forces you to watch the video to see the final image - which looks nothing like the shoulder-spiked, triple-forehead-eye'd villain of the game. Spoiler, the generated image is just a threatening looking green dude with two different coloured eyes.

It's a decent writeup on the process of trying to generate specific images using text prompts, I guess, with the conclusion that it's really hard, and in some cases basically impossible (hence the lack of the three forehead eyes).
