I took another try, and clipped the red Black Point much more, as shown here. This darkens the image a little. Less red helps balance the green, the grass is more natural, the sky is darker blue. It could be lightened with the Master Channel Midpoint, but since we have so drastically modified the image, our range will be somewhat limited. The Green and Blue were not changed, still the same as shown above.
Experimentation is desirable, but using the right tool helps a lot too.
