Pro artist who specializes in vector work here: I would use Adobe Illustrator to draw it, while looking at actual photos of pelicans and bicycles, and export an SVG. If it needed to have a lot of named parts I could make that happen.
If I had the latest version of Illustrator then I would consider seeing how well its image generation does, but I do not because it has a lot of exciting new bugs that break my normal workflow. I believe that under the hood that works by feeding your text prompt to a bitmap image generator and running the same old autotrace on it, which results in some pretty messy and hard-to-edit shapes.
