The first quick sketch I had made, with this i tried learning about how to get a glow around the edges of a model, to make the lighting look 2D

The secondary sketch I had made. here I developed and refined the 2D art style allot more with the blender node system, however it did not look like what i wanted, i wanted it to look more drawn.

With this version I focused on getting handpainted textures, these were made with blender and photoshop brushes, I also got a better glow on the sides of the ball, making it look allot more shiny.

Here I made some 2D illustrations to add during compositing, with this I was able to blend the 2D and 3D styles in premiere pro.

Here I made some 2D animations for the light FX, this was done in 12FPS to give it a more classic animation style, i also addes some extra movement in post and added some color correction.
