Hi Anita, that's definitely a vast landscape and very pretty too.
I also struggle with landscapes and it's about getting composition right as well as having a real point of interest. The question I have started asking myself is "why am I taking this shot?" and the answer of it being pretty isn't enough! I realise the theme meant we needed to get out and shoot something vast, so that's the reason but I found asking myself the question and searching for a focal point improved my landscapes a lot. For me, there are four rules I follow when composing, especially landscape:
Simple - fewer than 4 identifiable "things" (e.g. sky, beach, sea, boat for example)
Asymmetry - usual rule of thirds but also ensuring the four quadrants aren't mirror images of each other anywhere
Eye movement - using leading lines etc. to get the eye to move naturally across the image. Ensuring there is a clear "subject" also helps this and also avoiding clutter etc.
Point of view - is there a better one? Lower/higher/left/right or closer in or further out?
Not sure if this helps and I'm not meaning to be critical, just explaining how I've struggled with getting landscapes working (and I still can't!) but this has helped me...
