I watched a video on youtube on how to make photo look better and got some useful tips from that. I brightened up the woodland in the back and made the heath a nicer colour of purple.
I did similar things to this image. I felt it was still too green, so reduced that. I made the heath within this area a nicer shade of purple and finally I edited the sky so that it doesn’t have such a strange colour.
The woodland looked a bit odd to me as well. The trees were too green, but when trying to edit it how I usually do it reduced the green colour of the grass. In the second photo you can see that I made the tree trunk brown but kept the leaves and grass a good colour of green.
