I'm a bit late for #fedipaint but here's my contribution ! It's basically a ripoff from the Butt Fish from Vae Victis Miniatures. But not a recast or a hateful IAg recreation, I made it in greenstuff. Using the official model as a reference in Blender was incredibly useful, and I didn't have to conceptualising anything, ensuring I could focus on learning how to sculpt.
Limited by the #Zorn Palette (which I dearly enjoy), I searched for a suitable fish to reference, and I settled on the rainbow trout.
I'm very pleased with the result. My modelling is fine, and referencing a real animal for painting made the colors quite interesting.
