Did these animation tests in Unity. The concept for the snake/lizard gentleman was made in Krita, then the different parts were cleaned up in Illustrator and finally the rig and animation itself were created using the Unity engine.
The VFX is a "Devil summoning VFX" as the reptile in question is a dark summoner (But SHHHH, don't tell anybody!! It's a secret...). The assets were made using Krita as well and the actual VFX was made entirely in Unity.
