Only things I can pick at a glance are that your exhaust stains are wrapping underneath the fuselage. Erase the bottom section of it on the fuselage aft of the wing-root line and you should be fine.
That, and your fuel markers do not have any fuel markings. C3 or B4 or whatever was necessary.
You need to reverse the 'Nicht betreten' on the right radiator flap section, it is mirrored by the skin when it wraps.
Only the right side does this, so just horizontally flip it and you'll be good to go.
