lol honestly... ditch the fur... i really think you need to work on the design some... for example it doesnt really read as a maniac to me.

Read up on classical short story structures, like for example a standard structure for someone escaping or trying to get out of somwhere:
-they try and get out
-they think they have
-they end up back where they started

Empathy is so so so important, if people dont have someone or somthing to empathise with they just wont care. Make us feel sorry for him.

I know you dont have long but its really worth spending atleat 50-60 % of the time on the planning, also be aware that good animators do around 2 and a half seconds a day.. and this is your first film, make it shorter if its within the brief, if its not then do really really stylised animation. Look at things like south park or family guy, it isnt full body animation, you are going to make your life really really hard with all the action your planning in this.
