Managed to get some paint onto this thing.

Base coated black from a spray can (top done with a brush)

Layers of dry brushing from the black…

Chocolate brown (basically a tester can of house paint)

Additional layers of a tan mixed into the brown with more tan added as the layers went on.

Ivory mixed into the tan/brown mix.

I painted up the top separately

The white tube cap pretty much disappears inside the tube. I might add some Black around the rim to make sure it is completely hidden. (The two dry brush colours can be seen in the picture above).

The nearly finished tower…

Still the gratings to dry brush gun metal as well as flock around the base as well as get a green wash around the lower parts of the tower to simulate damp. I might even go so far as adding a climbing plant up the side.
