"Argus Filch, the shadow Necromancer"

An illustration made for a challenge on Digitalpainting.school :" Recreate a story for your favorite farytail or cartoon".
Imagine Argus Filch from Harry Potter. He's not only the stupid "concierge" of Poudlard without any magic gift, but in fact a powerfull dark mage who can animate the dead...
Happy New Year !!!
