Looking great mate!! It's nice to see people taking an interest in some of the less celebrated aircraft like the Canberra!!
One small thing though: the way you've shaded the fuselage makes it look a little less rounded than it should be. Here's a couple of pics of an Aussie Canberra from a museum in Adelaide. They show the way the light hits the fuselage - also has the alternate 'cockpit' setup the majority of RAAF a/c had.
Btw: The Canberra has to be one of the best sounding jet aircraft I have ever heard... the flying one at Temora flew here in Canberra last year for our 60th Anniversary VP Day celebrations, I don't think I'll ever forget the sound she made as she did a pass at 50ft above the lake!!
