Character design and planning for the step up and step down assignment

My next animation assignment is to make a character to walk up stairs and back down. It will step up in one emotion and step down in another emotion. My character will walk up tired and then puts on headphones to give him the motivation and energy to walk down stairs.

This the character I'm gonna animate. 

There must be a 5 second pause when he reaches the top. This

is my thumb nailing process of how my character gonna react when he 

look down stairs. 

Thumb nailing on how he is going to anticipate.
