First an initial sketch based on the reference material provided by Skulldog.
This character is named Sans and he's a kind of bird gator dog like monster.
Keys established describing the general motion.
Both these steps were done in Clip Studio Paint
Switching to TVPaint, The keys are translated over.
Some keys dropped or redrawn to better clarify the motion and focus.
Sans is going to laugh, so a "z" is drawn where I'll be jagging the motion.
Some laughter added.
More frames added and the laughter motion solidified. Face on the second key pose made crazier and goofier at the same time to better describe the character's personality.
Wing motion reworked to clarify silhouette and motion. Wing drop added to draw the eye down towards bottom third and add focus on face.
Tail added in and details start emerging. Back feet drawn in.
More details, feathers, puff more obvious.
And it's done! Now with shadows, pupils, and even more feathers.
I'm pleased with how this came out. I've felt my weakness in animation was "breathing", making the character react to moments with the way it drew in breath. So this animation challenged that weakness and had me experiment with more ways to suggest rapid breath (laughter in this case) and using breath as an anticipation tool.
