It is a human picture. Part of a series from the City of Wonders, if I recall.

I am over-the-moon about Agathe’s art. To me, the piece shows a strong influence from the style seen commonly in medieval woodcuts, and the use of color is spot-on.
I’m not sure how successful it would be to make them available as black-and-white coloring pages, though, as she uses a lot of colored or negative/white outlines, such as the nimbus of purple flame surrounding the figure in the bottom center. (But I agree, it would be fun to color them!)
