Nina, your sketches are fantastic. The people look true to life, and the planes and truck are excellent. If you aren't already an illustrator, you should consider going into that field.
Liselott, I like your airport sketches too - you captured a little of the boredom of standing around the airport waiting for a flight.

I like moustache-guy and the lady with the cane.
