My best advice to you on landings is: Avoid the tunnel vision at all cost. All newbies mantain his eyes on the plane during all the flight, when they want to land suddenly encounters the runway on out of course approaches. As was said earlier in this thread "the key for a good landing is a good approach." You need to develop the ability to see the surounding areas while your trainer is still in the air. You can practice this exercise in order to achieve this ability with safe: When your trainer is passing in front of you at a secure altitude give a glimpse to the runway head. Your brain will "take a flash picture" of your relative position with respect to your plane and the runway. Doing this when your trainer is in the last passing in front of you before the landing maneuver will help you a lot to improve your skills on landings.
