I wonder sometimes if we may end up with an over- saturation of 3d perfection...when I see handmade animation like Miyazaki's or stop motion like ParaNorman, it seems like there is great opportunity for individual talent or vision to shine through away from purely digital animation.
I started Zbrush because I have too many wacky ideas and concepts in my head and it seemed like the perfect way to make them happen, but most of my sculpting and painting has been physical.
I sometimes wonder what would happen if we had to create something on the computer without CNTRL-Z to bail us out...I think that may be the biggest difference between the way we approach physical and digital art.
Sorry to get all philosophical like that!
Thanks for your feedback, and all the best with your animation work
