Interesting how we all prefer different things. I like No3 as the sky colours are great and the waves bring a litte more depth. Saying that the first three are all good.
I can not make my mind up between #2 & #3 as I like the wave in #3 giving it more sense of movement but I would have liked a touch more of the clouds from #2.
Great photos
Great shots, Darren! I like them all, stunning colours! If I had to pick it would be #3 because of the reflected colours on the sea & the way you've caught the tide drawing out & leaving the wet sand, closely followed by #1.
