Looks really nice, but as a Necron player I know the risks of too much silver, and that is that you can come out looking very flat.
Your silvers need a wash to bring out the shapes. Everything looks a little monotone at the moment, with no noise to break up the spaces. I say first do a black wash to bring out the shadows, then a thinner blue wash to make everything look spiffy. You don't have to cover the flat areas. Just hit the crevices then wipe the large spaces you want to remain untainted by the wash with a q-tip, and viola, silver with deep shadows. It provides some texture and noise to break up the silvers.
