Sketching a Mural with a theme in mind

Here is a mural I did that was going to be hanged from a gym wall. The main reason they chose this option was to give them flexibility, they will be adding onto their gym in the future and this way they can rehang it without losing it. It requires a bot more work on my part, but the final product is fun to see. This school's name was Explorer, so I went with four great explorers in American history. Discovery of America, Lewis and Clark and also Sacajawea, finally the man on the moon. This is the lined sketch I completed prior to the painting process.
