Here I´m still playing with some cloud layers (4) to try to match the concept art look..
I´m using cumulus clouds and textures to cut down the shapes. I like the
turquoise blue fog, it gives me a sense of inspiration, but I don´t know how much is it affecting my relation to the concept art. I guess I´ll turn it to a dark blue later on and keep that way. Until then, I´ll use it because it gives a clear view and depth of the lower cloud planes.
