Number 1 has lovely tones and colours. Composition-wise I'd have liked to see a little more of the channel bottom right and the landmass to be slightly higher in the frame with a straight horizon.
Number 2 is a nice holiday snap, but it's a shame the end of the land is cut off.
Number 3 is the best of the set for me, with good tones and colours, a nice strong diagonal to lead the eye through and a focal point (Jabba the Hutt?) for the eye to rest halfway along. The glowing rock on the right does break the composition, but it also adds a brightness and warmth that the rest of the image lacks.
