Last couple of pics, I got two resin aquarium pices in The Range (UK store) for less than £9.. Bargain
Here they are all painted up ready for Salute.
Arch: Based onto a cd and blue foam added for extra masonry rubble. I might buy a couple more of these at a later date and muck about with them....
Bridge: I didn't have time to get rid of the crappy moulded vegetation around the base of the bridge, normally I would have either based up with rubble to hide it, or ground it away with a Dremel.
