Coincidentally i've been working on this for a while....

If you don't mind me asking, what font did you use for the 747-8 in front of the Boeing logo? I'd intended to put "Boeing 747-400" somewhere on mine, probably under "Intercontinental", but I couldn't find anything to use for that..
Aside from that, pretty good job. I think that the gloss effects on the fuselage are kinda killing the details on the grey lines above where the red curves back up (Especially on the grey area towards the nose), but a good job other than that in my opinion..
