Took these today with my FujiFinepix S602Z on a Tripod. I haven't done anything to them, but if you were taking them, how would you have made them look better?
polarizing filter on the shots with the pools would take the glare off the water and let you see into the pools.
the last shot of the rock pools with the sea, this could be improved using a long shutter speed to create a milky sea over the rocks (you would probably need ND filters for this).
composition wise the boats is probably the best of the bunch, it need to be straightened up and I'd place the boats lower in the frame so that the boats are pointing bottom to top, with the space above the boats or go for a wide angle crop to emphasizes the line of boats.
The rest of them are pretty 'flat' this is down to shooting on an overcast day, meaning you've got little contrast in the scene, this could be improved by shooting at a different time of day.
take a look at the following
