I love what youve done here! One nit is that the airport in the last picture (im guessing that is what that is) only has one runway. Even small airports have 2 runways at right angles (forming an L) with one aligned so it faces into the prominent wind direction. This permits craft to take off and land into the wind to get better lift and slow their speed, even as wind direction shifts throughout the day or weather patterns change with the seasons.
