After animating 2 scenes, i realized that something was wrong. In terms of movement, the animations are good, but the characters are not showing their intentions. Looks like they have no purpose.
Then i saw this http://www.animatorisland.com/?p=609
FUCK! I’ve never been used to drawing more than 2 sketches to test the posing on each scene. Now i understand what Avelino, my teacher at Melies, was trying to explain me. From now on I will always do a massive amount of sketches to capture the feelings and intentions of the characters before animating.
