ACK... all my Catechism classes just came back to me in a rush (and the horrible "What is Hell?" Film they made us watch.) EEEEEEKKKKKKK!
The cart reminds me of the Cauldron Born from "The Book of Three" (Disney's Black Cauldron handling the Real/Surreal animation)
Great job handling the surreal lighting and making the flame not look like cloning. The floor does look hot! Neat CHOP!

Good work. I see a depth issue...I think if you removed the flames that overlap the body of the wagon, it would look more like the burning door was in front of it and increase the feeling of depth. Effective image, though.
