English Textbook Concept Sketches and Snowboard Sticker

Sorry I haven't updated in a while but I wanted to throw up to small pictures. The first is of three characters. The characters are concept characters for an English textbook. The choses character would appear throughout the book introducing lessons, etc. I'm trying to decide which of the tree is best. The characters also have friends (e.g. the otter pirate has a seal, parrot, and dolphin friend) but I only wanted to make one character for concept purposes.

The second picture is a snowboard sticker I made for one of the teachers at my school. If you have an opinion about the English textbook characters I'd love to hear. Thanks.
