Having just had a look at a few of these images I think I much prefer this one. The first has a little too much wonky colour stuff going on - this has had minimal processing though. Literally two minutes pegging the black and white points and dust removal. I can't remember whether I used grads in this for the sky but i guess i must have done, maybe that's where the purple cast comes from? Also, I can't work out what that circular thing is on the bottom left - doesn't appear in any other pics so it must be a weird beach feature?
I managed to wipe that circle off with a bit of detergent so you shouldn't be able to see it anymore.
