hmm we're not really done yet.
you need to draw a line for stomach length.
you need to draw (lol) a slightly bigger circle then the chest one for the hips and stuff
then connect the sides with a slight curve. then seperate the legs into 3 segments
if you are drawing standing up then the hind quarters and below knee will be relatively similar in size, but if you are drawing smthn on all fours the below knee will be longer. also (u already know probs) the knees are backwards on animals
