15mm Empire artillery

Artillery in Sword and Spear Fantasy can be pretty devastating, but it needs to be protected. So, for my Warhammer Empire army, I've put together two units of Imperial great cannon, and here they are;

Clearly, in reality, each base should really only have one cannon and maybe some gabions but artillery is quite an expensive option in S&SF and I rather like the look of a crowded base in 15mm. I think that they will look OK on the table.

Next, I'm going to be finishing off the rest of my mounted Knightly Orders (men-at-arms on barded horses) and after than, I'll begin work on the infantry.
