Focusing issues...
Hello Robert,
Fortunately, you can always trim off the frame and start again until you find something you like.
Regarding the OOF (Out of Focus), it is always important to know how to focus, please no disrespect intended here. But generally it is not a good idea to use auto-focus on any landscape scene. The auto focus will take the lens to infinity, which will have direct reduction consequences for the depth of field. As a rule of thumb, you should use the smallest aperture possible and focus around one third into the scene. This is called '
Hyperfocal distance'. The other way is to focus on infinity, try to see the nearest object on focus, and refocus on that object.

One other thing I would highly recommend is the use of a really good tripod.
Hope this helps...
