ooo pretty. Glad you haven't gone overly blue with the hull colour, nice and subtle.
Tobias's can look a little too dark grey/blue sometimes; I'd say yours is pretty spot on

The colour in the nacelle 'vents' looks perfect

Don't know if you've finished them yet, but the blue strip lights under the nacelle hoods(?) should be brighter blue, leaning towards white, with some light spread down the adjacent surface. The same 'near-white' blue is used for just about all of the exposed light strips judging by screenshots (along the 'spine' on the top of the saucer, behind the deflector, nacelle hoods + opened fins etc).
