My first airport

At first glance, it looks quite nice, but there are lots of things to improve. Try using a ruler or any kind of guidance for the straight lines. Pay attention on the symmetry of some lines (ex: the hardstands). I'd also suggest you to make yourself a terminal building. You can be creative and use MDF wood blocks, for example :)

There are a few tutorials on Youtube about creating your own diorama. Check this one, for example. They might be very useful! :)

I wish you good luck! Please keep sharing your results with us!
 
Reminds me of when I first started with model airports. It's all in the imagination. It's a good start. The use of a ruler would benefit. Also, I have used the ruler measuring tool on Google maps/Earth and Bing maps to get an idea of measurements. Nonetheless this a starting point which is to be appreciated.
