I appreciate the "things you pointed out in the drawing", but you have to understand that he isn't drawing humans, but rather horses. The anatomy is going to look different. While we may never know how a horse will look like playing football, we can still get the main concept of how it would look like. I don't understand what you meant by sending a comparison of soccer and football? The character in the drawing is holding the football with their hooves and look like their running in the "correct" way as football is played. d279m997dpfwgl.cloudfront.net/… if you take a look at this image, you will see it is about the same leg proportions as the drawing Kaleido had drawn and the man is holding the football with one arm. If you still do not understand what I'm getting at, please ask any questions. I am not attacking you in any way, I am just trying to see what you are getting at and I will support my friend in any way.
