Above is the old man walk cycle I was working on for the Knockerupper project. It took me longer than I expected to get it to this stage as I’ve never done a walk cycle on an uneven and uphill surface. When animating, I constantly took in consideration the weight of the stick although my favourite part was animating the hat towards the end. It may not be the most realistic looking tophat, but based on the advice and tips from animation articles and videos, details like that can really emphasise movement. I have to say that I agree. I wanted the fragility of the old man to be very obvious but not too exaggerated, so I animated a bit of hat follow through on the exhaling and shaking of the head part. In the end I believe it achieves its goal of highlighting the movement.
I also found PoodleTime on Twitch to be extremely helpful with understanding timing, held poses and weight of characters (center of gravity).
