Makes annotated watercolour diagrams as one finished PNG for a post, lesson, slide or poster: soft watercolour washes with fine ink outlines and handwritten labels on warm paper. The drawings come from a picture model and every word is set in real type on top, so labels are always spelled right. Best as one subject painted large with labelled parts; other layouts work too. Needs a FAL_KEY or a Cloudflare Workers AI key; about $0.01 to $0.02 a drawing. Use when someone wants a watercolour or hand-painted diagram, an annotated illustration, or a labelled nature or science plate.

About this skill

You say

Make a watercolour diagram of the parts of a mushroom

It said back

I've made the watercolour diagram of a mushroom's parts: mushroom/explainer.png (3200×2000).

  • Layout: one large side view of a mushroom with six labelled parts: cap, gills, ring, stem, volva and mycelium. Each part has a short note on what it does. The subtitle reads "The mushroom is only the fruit; most of the fungus lives underground."
  • Check: I read the finished picture myself. All the words are spelled correctly, nothing overlaps, and the drawing has no stray lettering. In the first version the Ring pointer line cut across the edge of the cap, so I moved that label to the left side.
  • Accuracy: not every mushroom has a ring or a volva. Those two parts are typical of a few groups, like Amanitas. If this is for teaching, you could add a footer saying so.
  • Cost: $0.012 (one drawing on fal).
