Well, i've done a couple things myself (here my new airport: http://forums.x-pilo...s-airport-lg02/). I'm "playing" with blender last couple of months, and I find it not toooooo difficult, but very powerful. Watching tons of tutorials helped me a lot. I cannot judge myself if I can give something here, but I would like to try. Here is something I made in about an hour.
This is the control tower of Eleftherios Venizelos International at Athens, Greece, with it's support building.
Lighting is not that good, i put a couple of them just to take a picture!
