The figures look great - the Edwardian clothing will suit the layout perfectly. I can only echo Phil Parker's advice from a recent BRM DVD, which helped me when painting figures. White metal figures generally don't need primer (you can use car spray primer, which helps a little with painting). Glue the figure temporarily to a lollipop stick with superglue, it'll break easily when painting is finished. Start painting from the middle and work out to avoid going over bits that have been painted previously, so start with the face, then move to the shirt, trousers, waistcoat, hair, jacket and hat. Don't paint shirts white, use light grey instead as shirts weren't always perfectly clean and don't reflect the light perfectly. Painting figures does take time, the best thing to do is not to rush.
