Inspiration for this projet is “The Elves and the Shoemaker”

some ideas :

The first image I was playing with gravity , mainly inspired by M.C. Escher ( Relativity)

The second one is inspired by the story  “The Elves and the Shoemaker” and labor abuse.

I decided to take the second image and go from there (work in progress)

added brown color to the boot and sketched small men .
