I've made all the light and occlusion layers in the way that are supposed to be. Thanks to that, the rest of the process won't be as time consuming as I would expect.
Details I need to add:
-Clouds (most of them have to be purple)
-Blushed faces
-The sun (right behind Twilight's head)
-Refining the light
-Refining the shadows
-Details for the ocean
-Maybe some Twilight's tears of happiness. Or Tempest's.
I hope you like the final result and thanks for your support!
Love,
