So, this is now the army WIP proper!
The flame cannon. I'd quite like to do some bright green fuel leakage or cracks in the barrel, but it's much easier to just paint it brown I'll probably make the ground look scorched insead.
I toyed with the idea of colour for it (a red barrel, blue/yellow wheels etc), but went for vanilla brown. I do have another cannon which I might do this on, but the colours would have to be muted to fit in.
