I cant post on ic because of things
So i just wanna know how do one draw keyframes nicely so the motions inbetween correctly

Also i have drawn batman since baby but only recently i realize/can word out that the deltoid isnt just a circle nor is the head so perhaps a more comprehesive(and less wordy)
Means to draw/animate correctly may help.

Also i think most "how to animate" books arent enough for me so, what about that.
