That's a nice model, VERY nice workmanship, but I DO see a few problems...
The OAMS pods (bumps on either side of the rudder) are shaped wrong, the nozzles of the OAMS engines are VERY oversize, the wings are curved upwards (the wings are not curved up on the real shuttle) and the nose isn't shaped correctly.
Also, on a model this scale, I'd suggest that if the payload bay doors are going to be "openable" that the interior of the payload bay should be detailed accurately. Otherwise it doesn't make much sense to have the payload bay doors open at all...
Nice work, but you might want to get more detailed scale data, especially if you want to actually sell the model...
Good luck! OL JR
