That's a very unique camo pattern, I like it! Ship looks great overall--the color combination of the deck with the hull is a good match, I think.
I'll echo Ruckdog's comments--recommend a wash of some kind on the guns. Not that this is the right way to do it, but most of the metallics I paint on my DW ships are a combination of three colors, or two colors and a wash. For example: for my Chinese, the metallic parts were painted black, then they got a heavy dry brush of one metallic color, then a light dry brush of a second metallic color to complement the first. For the tesla coil on my Australian ship, I put down one metallic color right on top of the primer, then did a heavy black wash (Nuln Oil from GW), then a medium dry brush of a second metallic. Adds some depth to the "metal".
Can't wait to see the rest of the fleet!
