Blueprints contains errors 95% of the time. Always overlay a picture of the real thing (taken from far) to validate a blueprint before using it. Assuming you were using an accurate blueprint (which seems the case) blueprints doesn't provide "depth" and "curvature". You're right, there's nothing wrong with the nose when you look from the side (profile) but it needs some reworked curvature when looked from 45° to the back (135° from the nose, or 3/4 aft) Such kind of accuracy you can never get with blueprints alone.
Wing trailing edges. I've just installed Blender and found it thousand times more complex than another 3D modeling tool. So I don't know what to say, but you'd better find the technique to create sharp surfaces, and quick (like a knife, not rounded/curved on each side and very sharp at the edge) This will be required over the entire wing, the wingroot fairing (aft side - find a picture of an inflight A350 from below) the windows cuttings, engine pylons trailing edges, etc.
FYI, A350 wings have an "S" curvature (supercritical ?) on the underside. Something else you don't have with blueprints...
And you'll have to model the engines inside (at least for the exhaust cone) to improve the exhaust cone shape.
So... that's why you need at least one hundred pictures of the real thing from every angle before starting the project : compare your model with the real thing anytime from every angle/close up. You move one line/side/point/surface... check again with real pictures. (Precious advice I personnaly learned from Hiroshi Igami/Tenkuu Developpers Studios)

Something that has to do with materials settings.

You'll have to edit the contact points entries aswell. Moving the CG height will just change at which altitude the model will be loaded in the sim.
