Really nice wide fields Leon. The second one is very good. Like the colour as it's what your camera is picking up and when you try and change it it never looks as good as with the data captured.
A little bit of extra colour can be added just to enhance what you already have in your data using either colour balance which you can enhance individual colours or just saturation
Just basically process the data your camera has captured and don't worry about changing it too much. Your images are looking good
