Narrowing down the character

We are now defining the character's design and starting to model depending on whether our animation will be 2D or 3D or mixed. I decided I want to work in 2D for this animation so I can try to learn the Toon Boom program better.

 I decided on the Okapi design with the thick-ish neck and large ears. I thought it might be better to make him stand on 2 legs so that he is more expressive during the animation. I also feel like he could have a slight devious look during my section because he is planning to trick the rhino into giving up its horn.
