Awesome work. Try to do full-figures with your sketch studies, especially since part of the deal with A McQueen is getting the whole shape language of the entire figure. Also for your color final - I don't like that one of the guys is cut off/only visible from the torso up from behind. I would rather the scene be less staged action so as to err on the side of showing more information. Remember that concept art is a form of communication with other people on a group project - and also with that in mind PLEASE label your work WITHIN the image. Name, Project, Date, Subject Matter. Nice job.
