I think one of the extras you might consider would be a large eye oval eye morph to give the “ducks” a more cartoonish look! Perhaps a new toon lash option too for the gals.
I’ve got a cartoon Duckie about ready to upload to daz3d. In preparation, I’ve discontinued the renderosity genesis duck. At one point I thought of the cartoon version as an expansion to the current product, but by the end, a couple months of work later, it’s become its own thing. The body was substantially changed, reworked, the textures all new, mcm morphs were made to get the giant eyes to close, etc.
