I think No.4 is a stunning image and the mono version works well too.
Obviously, for anyone who, like me, is totally familiar with the location, the gross distortion of perspective may be offensive if we become too precious about such things. But, given that the huge proportion of viewers are not in a position to notice that, you can safely ignore it. What you have created - if not a faithful representation of the scene - is a stunningly beautiful picture. In one of Scotland's most over-exposed locations, that is no mean feat. Well done.
