I couldn't resist a little mouse as the ringmaster. Then, I researched circus wagons and created my own, adding a little Art Nouveau inspired flowers and details.
Some circusy lettering. I was also inspired by Mexican folk art a little bit in my concept and I was thinking about cut paper when I sketched this.
Some random flower sketches I actually did before sketching the hippo. I liked the fan look of the flowers and it inspired the fan the hippo is holding.
