Basing Empire war-machines

When I attended my first serious tournament, Polish sausage, it became clear that the convention was to base war-machines. So I have grabbed the opportunity to  have a go at building some bases.
 

The base shown above is one I have put together for a Helblaster volley gun. I have included the chap carrying the shot tray and a couple of barrels and boxes for extra shot. The war-machine crew only purpose is to indicate the number of remaining crew. Therefore it seams appropriate to include one crew member on the base, since once he is gone the machine is dead anyway..

I have also put together two bases for cannons. Each base was made by combining two cavalry bases. I believe that this gives enough room to show off the bases whilst retaining a nice compact look.
