That was an interesting project for me because I worked back to back with a 3D modeler. I took part as a storyboard artist and character designer. 3D artist made backgrounds, but first I concepted color sketches of each scene.
For me, there was a lot of work and very interesting new communication :)
I used Procreate App. for all sketches (on this project).
Final scenes vs sketches
For all sketches, I`ve used Procreate App.
