HAving hard time to analyze if animation is realistic enough...what's the determiner, say, in math.

i suppose there is control theory, observation, but i dont know how to compare when the subject or view are, different, say. What to do

Need suggestion to learn, animating stuffs? basically handdrawn but i guess realism is in 3d too. Maybe like a big resource, or just, ...plans to run for, 600k yearly profit/income. Like how much, and what to do for those kind of...schedule, employment. Or just minimum expected portofolio to get hired just about anywhere decent. maybe above 50k yearly?
