The first thing that came to mind was to extend the lions legs to give him a more dynamic pose. Clowns are the greyest animal in the circus...next to the mice who steal the elephants peanuts.
Right now, Leo's back end is bigger than his chest. If he was a bit more barrel chested it might help. As for grey animals, you could have a grey horse or maybe a grey monkey. Grey isn't really their stereotypical color, but if you need grey they might work. Fun pieces, Emily! The elephant is my favorite!
Thanks, you two!
