Massive Problem

so basically got to my lesson today to hand in the work and realized i have actually done the wrong sections for the video which isnt at all good, after spending hours on it. so the only option is that i have to do the sections that i unfortunately missed. as my time on this is going to be much shorter and i need to get them done as quick as possible i have decided to create and improvise the techniques of rotoscoping as i go along.
