B-WING COLORS

[GF]

I'm having a SMT B-wing built and painted by a very talented member which did a incredible job on his. I'm uncertain with the grey and blue grey areas, I want to be sure what should be grey and what blue grey. Here is what I came up with but I'm not 100% sure about some areas, especially the rear fuselage stripes, main wing center detail and the grey areas of the gun barrels, which are either grey or a blue grey. After further reviews I think the intake detail on the big wing is the same color as the fuselage and not blue grey,
Here's a link to great shots http://killbyte.da.ru/ Click on Alliance Ships then B-Wing.

Any opinions will be greatly appreciated.
