Cancelled Thundercats Movie Concept Art and Storyboards Art is by Dave Bullock, who works on Transformers: Prime and has done work for Star Wars: The Clone Wars, Teen Titans and more.
Meh, not that the designs are especially horrible, but it just feels like a step back compared to the new series. I particularly dislike Lion-O's face.
Dave Bullock LOVES some big ass out of proportioned arms doesn't he!? Sheesh! Glad they saw these and were like. Nah brah! WTF is Panthro doing with that long ass tail! YUCK
