Once all the basic colours had dried I gave the buildings a wash with thinned down burnt umber.
I also painted the ladders with the burnt umber wash.
At this point I had come to the conclusion that I wasn't happy with the finish on the tower. It was too smooth and also the spiral join in the cardboard tube was far more visible than I had hoped it would be at this stage.
My solution was to paint thinned down tiling grout over the entire tower. The grout is a grey colour so it will not need to be completely painted over, but I will need to darken it down a fair bit. The grout has a fine gritty texture and I have painted it quite a random way, so once I get some more paint and washes over it I hope the finish will be a little more successful.
