#1: Classic "above the rotation" angle, a bit too far in and too low on the pitch axis for my liking. Angle also does not really work with small aircraft. For effect, go with an A330+wingflex. Scenery is also bland. If you really want the MD-95 in there, then choose another angle, closer to the plane.
#2: I see the concept, but why is there a KLM 737 at TNCM? A 747 (now an MD-11 I believe, however) usually flies this route. Otherwise, its just another generic, boring angle. Scenery is nice, the angle is the only thing spoiling it. Position the viewpoint next to the engine perhaps.
#3: Nice colours, classic spotting angle. Scenery is, again, boring, and the cloud coverage spoils it a bit. Too many (broken) clouds. Too many clouds overall.
