In the Disney Animation feature "Aladdin", I created the character design for Jafar when he transformed into a Cobra Snake. Really cool character but a lot of work with all the pencil mileage! :)
Originally I thought it would be cool to have a skull design on the back of his hood but it was going to be too much work for the artists to inbetween.
Here's a copy of one of the drawings from my animation scene when Jafar was transforming into the cobra. The dialogue was " Perhaps you'd like to see how snake like I can be".
