Character Design - One of a Kind

Concept art featuring the main two characters of a project of mine. The story takes place in a dorm room, where two roommates - who both collect toys and merchandise - dislike each other. When nobody is around, the shelves come alive and the two groups of toys (much like their owners) are resentful of one another. However, UsaUsa-05 - an anime figure from a popular mecha series - becomes enamoured with newcomer Bunny - a one of a kind ball-jointed art doll. There's just one problem: Bunny is kept in a locked glass case - the key to which stays with her paranoid owner at all times. Will the warring groups join forces to bring these two together? Or is their feud enough to keep them apart?
