Here is the final scene.
Lightsetup: Two suns, one hard one for the reflections and a soft one for the lighting, a blueish mesh light for the fill light from the right and a soft environment sky light for the overall scene.
And of course, the final image. 
“Over the rainbow”
Modeled and rendered in BforArtists with some minor color adjustments in Affinity Photo afterwards. – This one is about the joy of aviation and flying around in a candy colored world. ^^
By the way, if there is a BfA 2.0 version coming, I would like to suggest this one as the next splash screen.
