Have to go with Peter on this. #5 is the nicest shot for me.
I can see where you are going with the beach hut's in #2, but something just isn't right.
#4 has far too much black foreground for my liking, but might appeal to some.
For me, #1 and #3 are not strong images. That wreck is actually really difficult to use. Been there myself and failed! The cliffs are spectacular and hold great promise, but this shot just doesn't do it for me. Sorry.
