I have been experimenting with new materials for my Mordheim buildings. Most of the tests were failures, so I settled back on tried and tested for the upper floor of the Smithy: MDF base and walls, coffee stirrer flooring, balsa wood beams, and pumice paste as texture filler.
The bottom floor is only missing debris and details (anvil, wheel barrows, etc.).
The mix of textures is very effective and the real wood gives the structure a slightly warped feel, which seems right given the exposure to the elements.
