To create this render I was inspired by the myths of the Wendigo and Ithaqua. I imagined what would happen if an unfortunate hunter met the ancient god of the snowy forests during his hunt.
To build the scene I sketched the idea and then sculpted all the parts in Blender. For the render I used Eevee and a little bit of chromatic aberration in the compositor I spent 5 days since I draw the concept until the final image. Sweet nightmares!
