I used the whale model from my previous post to try myself at clouds, and for half a day of work, I think I came out on top of it.
The cloud tutorial I followed was the one by Blender Guru.
There they fly in the sky.
Picture without Depth of Field and a little bit less amout of whale in the picture
Added Zeppelin for size context.
Changed colour palette to emulate dusk/nightfall. the location of the sun will probably be improved upon.
Added some more details in the background as to fill void.
Boom! Three Screens! Now with even more whale than before!
