Backgrounds made for my 3rd year animation film "Grindeberg's case"
Those are for a part of the movie where Elizabeth tries to resolve the case and put the pieces together in her mind for the first time in the film.
It's a place filled with cardboard boxes, representing her mind being poisonned by the thought of her retirement, red strings, photograph clues, papers & journals from her past, representing her nostalgia of the "good old days".
