Below are some of the extremes and key drawings from one of my favorite shots I animated. I like it because it is always fun to try to make the character appear to think about something. In this shot, Rico asks him if he would happen to know of a good horse to take. The Sheriff is trying to think about it and dig deep to answer Rico as Bucky is showing off in the middle of the background. The Sheriff's line is "A horse? A horse...Let me think... I reckon you want a fast horse, hum? Real fast? Of course he also have to..."
Here are some rough first pass drawings. This is how I start to rough out a shot after I plan in thumbnail form.
