doh' yes, me stupid, I could have made it different then
btw, a little suggestion: the window recessions on the engine section are that wide for pcount (originally there was a recession for each window group). It could look better if the windows cover at least 60-70% of those recessions (I'm thinking expecially at those on the top area), maybe using parts of other textures.
about the engines: it's up to you obviously, btw I remember I made a little different thing than the

model
The black texture with those grey stripes at the beginning and at the end of the engine section just suck in my opinion, and I modifyed (compared to

model) the areas where it was going to be applyed.
I imagined a rounded part surrounding a blocky nozzle, but I admit I haven't realized it very well, the blocky extrusion of the nozzle was too thin and short.
btw the engines could be done narrowing the hole of the nozzle (a little wider blocky extrusion) and making a deeper hole
Now, it seem that you modifyed a bit this area of the model, removing the blocky extrusion, and you probably modifyed also the other part where this texture is used, at the beginning of the engine section.
It's not a problem to me, as said it's up to you, and the result isn't bad (I just don't like that texture in the original model too).
I said that just to let you know how I imagined those areas, if you need some inspiration
