So here is my first sketch of 2 children biking and I showed it Greg Newbold and he gave me excellent advice. He said it might be better is the children were animals like a penguin and a polar bear so that more people can relate to the piece. I sketched a lot more figuring out what animals to use and what they look like.
Here is what I came up with, but I wanted to push it some more in making the characters and bike into simple shapes.
Here is the final sketch and now I am going to paint it!
