The issue for Claude is that Anthropic don't have an imagen that I know of, so the only tool available for the LLM to draw something is to start doing vector stuff in CSS, which is very hard for it (see the pelicans).

Gemini, ChatGPT or Grok would find this a lot easier as they could gen an image inline, although IP restrictions might bite you. Even Grok wants to lecture on IP these days, but at least it's fairly trivial to jailbreak.
