I'd say the last one could do with a wider crop at the wing tip, looks a bit close for comfort to me. Apart from that, it looks a bit unlevel (but I haven't used a ruler tool or anything, just looking at it).
As for the crops, I agree with Darren. You need to use 3:2 ratio (1200x800 is an easy way to remember, and what I use).
