Welcome to EPZ Matthew, and especially to the critique gallery.
We dont steal photos or mods to sell; image size would make such an enterprise quite foolish.
Its a nice scene. Youve done quite well as it is one of your first shots.
You are using the control modes of the camera, so I assume you have progressed to understanding what Aperture and Shutter priority are all about.
In this shot, you used Shutter priority; this is a doe you would use if the subject you were shooting was moving fast, and you wanted to freeze action; here, Aperture priority is the better choice, as it the depth of field you want to control primarily. Though speed is of course important, as long as its at least 1/60th you will be fine.
ISO 400, in bright conditions, is useable, but quality will be better at ISO 100. This should be your default ISO unless the light dictates you use higher; always use the lowest ISO you can.
So, ISO 100, at f/8, would give you 1/125th for your shutter speed, ideal.
Using +1 is a good idea when you have a lot of sky and sea in the image.
So how does the image look? Its quite bright, having low contrast; it not overblown, so perhaps +1 was a little too much, whereas +1/3 or +2/3 could work better?
That small piece of concrete lower left could be removed?
The horizon has to be level with a shot that shows it clearly, and in this you need a degree of clockwise rotation.
Then theres the overall tone, which for a bright, sunny day, albeit April looks quite cold, and blue.
Auto white balance will remove and warm tones that are present, so you cant try setting your WB to sunny for this particular shot, as the light is provided by an open Sun. Nikon, to their credit, have introduced a new AWB mode that retains warm colours, acknowledging that this can be a problem.
I have uploaded a mod that incorporates what Ive mentioned above. Scroll up, click the modification tab to view; view it large if you have the option.
