Great paint schemes!

Indeed, I have some reservations about that F27.
For a main reference I'm using this photograph, which btw. shows the very same aircraft You've portrayed in Spanish colors.

Going from nose to tail:
1) nose seems to be slimmer;
2) cockpit windows - the middle one seems to be much more narrow, relative to other ones, I also have a feeling that they should be all 1, maybe 2 pixels higher;
3) the antenna below the front part of the fuselage seems to be further back, and attached higher, although that could have changed over time, so I'm not insisting;
4) wire antenna seems to be attached to a small mast;
5) the radar dome seems IMHO to be "beginning" lower on the fuselage; also it lacks shading;
6) both engine and underwing fuel tank on the blank lack shading along the upper edge; I also have some reservations about exact shape of the rear part of engine nacelle;
7) there should be a warning light on the wingtip (I'd also suggest applying a lighter shade along the upper edge);
8) trapezoidal shape of the fuel tank hardpoint should be IMHO more pronounced;
9) there's something missing here...
10) actual windows seem to be all ellipsoidal, while Yours seem "straight, with rounded top/bottom";
11) doors on this side looks smaller - such large doors are on the opposite side of the fuselage;
12) IMHO that black line suggest rather different fuselage shape than in reality - to me it implies the circular fuselage that abruptly turns into a vertical stabilizer, whereas in reality it's more "subtle"

13) the tips of the horizontal stabilizer actually have a profile similar to the wing profile, so it's not exactly a precisely horizontal line;
Sorry for such shower of criticism, but actually You asked for it.
