This is old, but I picked it up again recently and added some finishing touches.
This is the witch from my Hansel and Gretel project I did for Lisa Keene's visual development class at Cal Arts. She is disguised as a wealthy widow in an extravagant mansion made of gold, rather than a house of candy. I set the story in the 1930's during the dustbowl. Hansel and Gretel are poor farm kids that dream of the glamorous Hollywood lifestyle they've seen in films and advertising. I imagine the witch descending the staircase to be captivating- a perfect embodiment of the glitz and glamour the children dream of. I tried to make the entryway glisten with gold yet feel hot like the inside of an oven. Foreshadowing.
The witch is represented by the color green, representing money and agriculture- two things the children don't have. With all of the crops dying, there is very little green to be seen.
