Hi Vacajun,
That is just lovely! You have captured the shape of the uc pods really well and it all looks great. You might try adding some variation to the fin shading. Even though the area is more or less flat, I'd add a couple of percent black, say 2%-5%, to the top right of the fin, under the stab, and fade to zero as you go across to bottom left. I don't know how they came to be called Big Uglies, they are the most beautiful jet transports ever to grace the skies!
