Started working on the sky part of Sea & Sky... I'm almost up to the point where I'll change colors to the darker aqua blue. Two more courses on each end (one in the middle) and I'll be switching.
In the water I wanted to show the various currents (surface currents and deep water currents, waves and eddies and the like).
The sky itself doesn't actually move - it's the air currents that I want to envision. The goal is to create a feeling of motion that is different from the motion/chaos of the water. Something more unified and subtle.
So far I'm liking it.
