Have to admit I am not the worlds greatest at landscape so hope you don't mind my input.
To the right of the image is an 'empty' space. Try cropping this out to fill the picture with trees as a background. Also although the sky is a lovely shade of blue there is very little drama going on so crop out this down to the tallest tree. Finally if the weather was that windy then why not try a longer shutter speed and get all that fantastic movement with the branches and leaves. Sorry just realised everyone else told you to slow the shutter speed!
If its helpful, when I am out with non photographers I just explain what I am going to be doing and for them not to wait as I will catch them up. They usually hang around anyway to see what the image is like when I've taken it. Never underestimate the interest other people take in your hobby!
