Theme or Visual Direction of Final Assignment

I would like my final assignment to follow in a similar direction as the second one. I think my narrative was strong in that video, but there was not much room for showing off modelling abilities and materiality was limited for the box that I was animating. So in the next video I would like to combine a similar narrative but perhaps with a more interesting protagonist....

I am really interested in finding ways of making the combination of visualisation animation and real footage seamless, and therefore I need to use/create believable and appropriate materials for this. For this video I would like to add another aspect to the narrative, which I am still thinking about. However, I think it would be interesting to change the scenery to something everyday and small scale- like someone's room, and make everything in the room look large. I am not sure how far I can go with this, but it might be fun to first make it seem like the protagonist is building-size and then show it as something actually really small.
