Here, I partially filled out the ex sheets for you.
I marked off all the beats and bars to the left.
Each key pose happens on the beat that is numbered next to the drawings.
I wrote which beats had what lyrics and how many inbetweens to get to each post.
Note that beats 6 to 10 re-use a few drawings that cycle left and right.
So you don't need to redraw the same drawings over and over again. Draw them once, then repeat them where the ex sheets tell you to.
