This is the Romulan Warbird 1:3200 from Round 2/Polar Lights (2019 reissue). Its basically an out-of-the-box build with lights added (smd LED lighting strips for both window lighting and the warp engines).
I looked at photos of the studio model(s) (which seems almost a grayish brown) and on-screen references for the base color and tried to stike a balance between the two. As my first completed build in almost 20 years, I'm fairly happy with it.
