Bill, I like the basic idea here and dumping the white studio scheme in favor of metallics. What further steps do you have planned? Right now it just looks like you need to work in some more colors to break up that dominant silver-ish looking color you've got on all the plating. Maybe get a dark color on the sword handle, or maybe do some of the plates another color? Since their shoulder and leg armor is basically three layers you could maybe change the color of one of them.
I do like that you want to keep them grim and business-like. These elves have a bit of an edge to them.
