Back when I had the chance to do a class with Christi Friesen, we made little koi ponds with resin for the water. It was a great project… and I haven’t used resin with clay since.
Here’s another fun miniature scene that has clay and resin. NerdECrafter has a fun video with all the details to making your own project. I think the end result looks a little minecraft-y due to the cube shape but that’s only a bonus in my household.
