try taking landscape images in early morning and late evening - the light lets colour and saturation appear stronger
try using a tripod or anything that can act as a stabiliser for your camera to avoid camera shake
think composition (although you could crop your image later on the computer- take your time to “make the picture”)
think story - slow down and think about what you are doing,
On the other hand- why not experiment, you can have fun and learn something
use something of interest in the foreground to lead into your picture and create a sense of depth
stand on higher vantage points give you a commanding view, (but take care and find secure footing on slippery ground or wet rocks)
