Looks like you had a wonderful day on the beach though it does not look in Photo 1 as if you were in the danger of getting a sunburn ... was it as cool as it looks with all those clouds?
(We were at the beach last weekend on Saturday and it stayed pretty cool with clouds that would not shift all morning, and then, as of 2:30h, the situation changed COMPLETELY and within minutes only ALL the clouds disappeared and gave way to a clear, blue sky with a lovely sun out, what a change in that short period of time!!!)
I really like Photo 1 here very much, and you and your feet look nicely tanned already, so you cannot have had only overcast days on the beach

...
... that photo of the funny sign on that rocky jetty ... I think you should have made a decision for either of the two elements: jetty only or close-up of the sign (and that sign is worth getting a pic of its own with the elegantly-throwing-herself-into-the-waves-lady

)
Photos 5 and 7 show a very common mistake in photography across large expanses of water: the horizon in both those pictures is crooked and it looks like soon enough all the water will run out of the side of your frame

. When you get it wrong (which happens to me, too!), there is an easy means to get it back to strictly horizontal in any post processing software.
