Observe, Observe, Observe
Despite the amazing and impressive advancements in the field of computer animation, it is still a challenge for animators to depict realistic type of human characters. You can do it if you are highly observant about the way we move, behave and react because you create from observation. I think famous painters got so much respect because they mastered the subtleties of the human face and structure, even the slight shadow beneath a smile or an eye movement didn’t go unnoticed. Mark my words, observation is what makes creation possible.
