Reproduction of Moebius’ ‘Le voyage d’Hermès’

Moebius was commissioned by Hermès in 2011 to create nine illustrations for a campaign called Voyage d’Hermès. This is one of those and like the eight others, no Hermès product appeared: Reference illustration: A huge wave splashing at the top of which is a soaring man. A long bird with blue body and orange wings is next to him in the orange sky.
I sketched it on my 30×30 cm watercolor pad:

For the outline I used a 0.05 mm Uni-ball Pin pen:

Then I washed the paper and applied some yellow and a bit of orange:

I continued painting the figure and the bird, the skyline, and started with greens and blues for the wave:

A couple days later, I tried a digital version of it which I finished on the same day, using Procreate on iPad Pro, 1878×1440 px:
