Beautiful!
As an old hand, you'll probably laugh at the question, but I ask anyway: Did you ever consider using watercolor with a dip pen instead of a marker? Season the nib with oxgall and paint the watercolor on the nib with a brush. You can stay true to pure watercolor and the guaranteed ligthfastness of your high quality paints - as opposed to whatever garbage the Chinese filled your commercial marker with.
Coincidently, I have a maritime painting of sorts online, albeit not as handsome as yours. Gouache, not watercolor. BTW, gouache works also in a nib, if it's thin enough.
Thanks Folker I'm glad your suggestion, consider that in any case I hardly ever use the Chinese marker, once in a hundred.
But I think I'll try a good ink tank with a nib.
I used it 40 years ago LOL!
You are fantastic!!!
Grazieeeeeeeee
A big hug.
If you want a fountain pen, try the Super 5. It's inexpensive, and it can handle waterproof inks for sketching + colorizing. Converter available, so you can use any ink you like (the Super 5 ink is quite expensive).
