I disagree. The task asks for an SVG; which is a vector format associated with line drawings, clipart and cartoons. I think it's good that models are picking up on that context.

In contrast, the only "realistic" SVGs I've seen are created using tools like potrace, and look terrible.

I also think the prompt itself, of a pelican on bicycle, is unrealistic and cartoonish; so making a cartoon is a good way to solve the task.

The request is for an SVG, generally _not_ the format for photorealistic images. If you want to start your own benchmark, feel free to ask for a photorealistic JPEG or PNG of a pelican riding a bicycle. Could be interesting to compare and contrast, honestly.
