Have a look at some of my photos of my 1:200 scale model. It's of my designated area at Jubilee Gardens. I positioned it with the right orientation and sunlight to get the effect of light/shadow on the site.
It took me just over a day to complete. Materials used include timber (ply, skewers, toothpicks), card, cloth, paper, plastic, polystyrene, thumb tacks, pins, grass, drinking straws, masking tape and glue.
On another post I'll post photo montage ones where people and background scenery have been inserted after Photoshop work. If you see a little black rectangle standing alone that's my mock person giving people scale for when I work them in Photoshop.
