Really good looking minis. Just a thing : if you plan to use miniature buildings, perhaps you should base your figures on washers instead of thick plastic bases : not speaking of the (cool) fact your figure will be 100% full metal, it also gives a nice visual effect (the figure looks like more a real pedestrian on the floor than a statue), and it also keeps your figs at a reasonable size including the base.
And to give the other side of the coin, metal bases and washes don't do minis justice with a hump of metal/scenic scatter in the middle, cut/clip off the metal bases and drill and pin them to either a slotta base, (and 20mm rounds are available from EM-4 for a start. Also that opens you up to a world of themed resin bases from the likes of Fenris, micro-art etc....
Ying to your yang!
