I absolutely love my Normandy statue but the grey is so prominent, it makes the sleekest ship in Sci-Fi look drab, and a bit busy, if you ask me. I do like the change in Alliance colors to blue/white/grey from the seemingly ubiquitous red, white, and black that the SR1 and all the other Alliance ships we've seen so far have. If the centerline Grey on the Alliance SR2 was white it would look a lot better.
Some minor paint flaws on mine, none with the outer hull, although there seems to be a bit of a difference in geometry for the port nacelles, like they got bent slightly inward. I seem to be lucky that my SR2 has no blue bleed, though the engine effect decals are marred, though that is the tiniest thing, really.
Overall its not on the level of a couple other sci-fi ships I have here, a Babylon 5 Starfury and a QMx Stargate F-302, but those were both more expensive, and are far more fragile. I'd compare the build of the SR2 to Sideshow Weta polystone, actually, its heavier than you'd think for its size, and the balance point for the base is perfect.
As far as the painting goes my guess would be that they're primed and the basic colors are applied in a mass-produced style with individual painters doing the fine detail work and applying the important detail decals.
I did do a drop test and it held up, but the most breakable bits would have to be the "fangs" on the fore of the ship, the front intakes of the nacelles, and the "because its cool" wings on the aft of the main hull.
I can't wait to see how the Cerberus variant looks. The gleaming reveal of that ship in ME2 is one of the best moments in modern gaming, to me at least. Alliance SR2 screams "warship" but Cerberus SR2 is built to impress.
Hopefully if these are successful BioWare and Dark Horse will look into releasing other famous Mass Effect ships in miniature, The SR1, Turian cruisers, Sovereign, Shadow Broker Vessel would top my want list.
