hello and welcome to epz.
the sea is a wonderful thing to photograph, constantly changing and moving, gives endless possibilities.
there are bits i really like about this shot, and bits im not so sure about so il try to explain.
banding the composition is fine, its difficult to do well direct facing the sea with no dioagonals what so ever but it can create contrast problems, the sky here being significantly brighter than the sea. the result is that the sky is brighter than it probabably looked at the time of taking, the best option with this is to use a neautral density graduated filter to hold back the brightness of the band of sky and even out the exposure to give you a better representation of what you see at the time.
given that you have this, i have to ask does it need the sky or could it be cropped off to concentrate on the sea.
using a foreground to link the front with the mid distance and into the distance is definately a good thing to do, but here the wet rocks with black tones and brightened by flecks of bright coloured seaweed are sinificantly more interesting than the dull rock on the base line and i wondered if you could have repositioned to use this black wet ridge more effectively.
although not a problem at all, the 55 mm focal length is an unusual choice for a sea scape, the wider end being used more often and easier to create the lead in lines which the wider angle tends to exagerate. similarly, the f22 setting is getting past the best zone or sweet spot of your lens and with a wider angle and a setting of f11 to f16 you may be happier with the results and in turn this permits a slightly faster speed if you are handholding which will make camera shake more avaoidable.
so i love the black wet rocks with sea weed, the spray breaking into threads above the rock, the rolling waves.
not so sure about the pale uneventful sky and the foreground rock
its not a bad shot, just showing you a different way to think it through
hope this helps.
