They came out well, Eric, but do straighten the lances on the horseman.

I like the way the cannon piece came out; it's a great vignette.
Over the last few (ok, maybe more than a few) years, I've taken to sanding out any roughness on the armor and blades on metal figures, then polishing them with a motor-tool and jewelers rouge. They're then stained with a mix of black and dark brown and/or dark blue oils. Additional highlights are burnished in the the side of a needle (old trick). 54mm and larger figures are fairly easy, but smaller figures can be more problematic if the detail gets tight.
Cheers,
Glen
