Hi there! Finally in my spare time , I managed to sculpt Vinnie from Biker mice from Mars, one of my favorite cartoon when I was a child! It's just a sculpt rendered in Eevee .I wanted to try the Vertex painting on the newest version of Blender and it's not bad! still experimental, but works fine!
Great work👍! One of the rare examples of someone using "Vertex Colors" for painting a model.
I hope that there will be a "Vertex Color Alpha Channel" and no limitation for the number of vertex color layers. Following Danny Mac's course "How to Paint in Layers using Blender 2.8" (https://cgcookie.com/tutorial/how-to-paint-in-layers-using-blender-2-8), you could paint an "Image Texture" and bake it to "Vertex Colors" using the workaround in Blender 2.8 and 2.9 that I describe here: https://cgcookie.com/questions/12965-use-for-baking-textures-to-vertex-colors#answer-44963 . So, you could combine the advantages of "Texture Painting" with those of "Vertex Painting".
