Invisible Architecture-The Letter Collector

These images are the first concept ideas for my new idea for the invisible architecture project, The story is about a 1000ft tall ghost who lives in a giant house on a hill over looking town. He comes out at night to carry out his favourite hobby... to collect letters from buildings, shop names etc. He takes these letters to a roundabout to write stories, poems, anything he likes, the only problem is finding the right letters , the right size, the right colour for it to look just so. He then goes back to his house just as the sun is starting to rise, and sits in his big crooked house that is full of letters until the next evening falls.
