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:
Outline done in thin black ink
Then I washed the paper and applied some yellow and a bit of orange:
Yellow and orange gradient on wet paper for the sky
I continued painting the figure and the bird, the skyline, and started with greens and blues for the wave:

Final version, 30×20 cm:

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:

Final result:

Horse and young woman in kimono under Sakura

I found horse and young woman in kimono under Sakura, another beautiful work by Taiwanese artist Jung Shan:

Although I have some rice paper, I am far from comfortable with it, and the ratio and size wasn’t what I wanted, so I sketched on my 30×30 cm watercolor pad:
Light pencil sketch on a large square watercolour pad
I used a Pentel black ink brushpen for the outline and strong parts, and was happy with how her faced turned out, compared to the pencil sketch:
Inking in black of the horse, woman and kimono
I used sepia watercolor and a fine brush for the tree branch and blossoms:
Branches and blossoms painted in sepia
With more sepia, some lamp black watercolor, and a regular brush, I painted the horse and the woman’s skin:
Horse and woman's face painted with a mix of sepia and black
And finally, I used quinacridone rose to paint the blossoms and the woman’s lips, and used what I had left from my sepia wash for the kimono, and the background. The rest of the kimono was painted with lamp black watercolor:

Here is the final version (23×30 cm), framed:

Samurai

This is ‘Speed III‘ by Jung Shan, who, as far as I understand, draws digitally and then adds actual ink brush strokes :
Reference artwork in black and white: a focused-looking warrior with a long flying ponytail, feet wide apart, wields a sword. There are movement strokes.

I sketched the samurai on a Moleskin watercolor book (21×13 cm):
Rough pencil sketch in a wide watercolour drawing book. My pencil is seen on the table.

I used a Pentel brushpen for the black strokes and cold grey Faber-Castell brushpens for the rest:
Inking with a black Pentel brushpen and cold grey Faber-Castell brushpens for the rest of the clothes, face and ponytail.

Then I erased the pencil marks, cut diagonally one of my cheap brushes, prepared a lamp black wash, took a deep breath and stroke:
Large black ink strokes. the brush is visible on the side resting on the porcelain palette. I trimmed it diagonally.
