airliners.net has extremely high quality standards. Sorry to say so, but your photos are nowhere near meeting these standards. (Neither are mine, so no offense intended
Please do not let this disappoint you. It takes a lot of time and patience to learn how to make good photos. If you are interested in photography, keep practicing. It will be time well spent
Some general advice, if you really want to learn about photography: start learning what the various settings of your camera mean, and what influence they have on the pictures you take.
Most important settings are shutter speed, focal length, aperture, ISO / luminous sensitivity.
(Sorry, I don't speak Dutch, but in German, these would be: Belichtungszeit, Brennweite, Blendenöffnung, ISO / Lichtempfindlichkeit.)
There is plenty of sources both in books and on the internet, that will explain what is behind these settings, and how they influence the photos you take.
Good luck, and keep shooting!
