Go to a beautiful place.
That seems simple but it is the base for a nice landscape photo
Find the Right Composition during the day.
you can see better during the day and it easier to find the right framings
Balance the Right foreground element
This is probably the most important point for me in composition, finding the right foreground not too small not too big that helps communicate a strong story and give a sense of depths and from where to look
Follow the Leading lines
Again this helps direct the eyes and to give depth and interest to a photo
Avoid High Frequency textures.
probably the most frequent error I see, lots of sands and rocks that are confusing to see
it is a great way to be sure your exposure is right on, and you can easily synch a retouch from one photo to the next in Lightroom that way
Use a tripod with a self timer
Make sure you are at 100 iso and your photo is sharp
Manual focus on the Middle Ground
At night the focusing can be off by focusing on the main subject manually and zooming in with you lens to be sure you are sharp is super important.
Play with Long exposure
When you have Clouds and water long exposure is a cool effect. I recommend .5 second for waves.
Slightly under expose your photo
The best way to get the best sky while still having enough light for your main subject
