On this tutorial, @Loopysue show how to improove the map color at the end of the creation.

Personally i feel more comfortable importing the final image on lightroom to retouch some colors.

Now time to decorate your landscape if you want... or not

Some red mushrooms, horse, eagle flying (More eagles in different position will be nice to make a group them flying) and a tower on top.

Ready to go!

Cheers

Add some Countour in the river to get a blue little bit different from sky

Add some Waves in Symbol Back Sheet

Selected LAnd Sheet, add effect - Edge Stripping, and chose one that fits me to upload in the work.

If you dont know how to add this effect @Loopysue made a great tutorial about it:
