I used a free model from Kiku Hoshimi - Download Free 3D model by Tokisaki (@Kuuhakunai) [5854e1b] (sketchfab.com)
The way I shaded it was similar to matcaps in Blender. I think it’s possible to use matcaps in different lightning solutions so you can have full control over the shading. I followed a few youtube videos to for tricks and tips. The beach background is an image.
Problem I have is the shadow. Shadow on toon/anime shading should not follow exactly the model itself.
