I started this as part of the CGMA mattepainting course, from Anthony Eftekhari. And I kinda got lost in the clouds and pushed it further.
I love clouds and I always struggled to integrate them the way I precisely wanted, to be consistant enough and interacting properly with the environment. But painting, makes me able to develop it the way i wanted! So yeah here is the final image!
This a bit reversed from what I usually do, as I basically built the image with matte-painting first and then lay and match the buildings in Blender to fit in.
