Hi Georgina,
Straight - Worth getting it the way you wanted. Are you lying on your stomach just before the threshold? I hope nothing was coming into land

Unattractive - Such a shame that such a fine looking building has been abandoned. as you say, unattractive in it's current state. I would never have guessed the second shot had been a swimming pool in a previous incarnation, it looks more dock related. Interesting juxtaposition of the stillness of the pool with the motion of the sea.
Shadow - I thought wind gauge rather than windmill, it is an odd shadow. Well spotted and captured.
Beautiful - I agree, it is a beautiful view. Captured really nicely with excellent colour and an interesting set of coluds too.
