@ooosssay These are great, thanks! Nice to support designs from Mexican road signs. Some of them could use to be tweaked for legibility but they're fine to start.

Represent ponds or lakes

This image is really fitting, duck + typha is exactly the image I would associate a pond with, too.

I noticed, though, that at 15x15 the image is not really legible:

(The duck maybe, but the typha could also be some person pointing to the right)

Don't know what to do about that, though.

I'd probably make the duck bigger and draw maybe one or two cattail reeds instead of a bundle.
