The purple fringing on the branches in the upper left of #2 (this page) is pronounced to the point of being distracting. Depending on what you're using for post processing, suggest carefully creating a layer on that area, sampling the magenta/blue color and desaturating it. I can't remember where I learned that, but it comes in handy.
Here's an example, cropped from the upper left corner and enlarged. I selected the very top left and desaturated it, leaving a good portion of the purple fringing to demonstrate the effect. you can see it along the edge of the tree trunk and in the branches in the center.
