iPad watercolor: sailboat and island

After rough sketching, I painted the sky, using the watercolor tool of the Tayasui Sketches app that doesn’t “dry” until you tap the drop icon. While the paper was “wet” I added blue to my purple wash near the horizon:
Rough outline of lines and shapes. The sky is painted blue and purple in watercolour.
On a different layer, I painted the sea:

On a third layer, I painted the rocky island, including the fort. I erased paint from the sailboat and the surf around it. And added a few strokes of different blue on the sea layer:
Brown of various intensity added to the islands, more strokes of blue over the sea.
Then I painted the fort red, darkened the rocks, erased paint where the seagulls were, and painted the sailboat:
I painted the fort red, darkened the rocks, erased paint where the seagulls were, added a red stripe to the sailboat and white foam around it, removed the layer that had the sketch I applied my signature and date at the bottom right.

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:
