I'm finding it fun to try to combine acting with drawing moving animal. Example when animal moves out of view i like to try to create a couple drawings. Its also fun to try to draw sequential drawings of dog movement from imagination. I slight tip that may be helpful when drawing fast moving animals is to start with say two front legs or two back legs then using some anatomy knowledge try to complete rest of figure. One reason why im finding this helpful is because of how sometimes the front arms and legs overlap in complex ways and make it hard for me to remember if i dont start with drawing them. I'm also finding it fun varying the background when drawing digitally. Hope you find this helpful.
