Greetings to all Cartographers!

I want to show you my latest work. It's hand-drawn map of western kingdoms of the Conan Barbarian universe.
Mixed technique: Pilot Parallel Pens, Pilot Plumix Pens, Promarkers, colored pencils (Faber Castell Polychromos), Pigma Micron.
Oryginal format: B2 (70,7x50cm).

The map is in Polish.

I don't have much experience with the top-down perspective., so I'm interested in your opinion. What could I improve in my drawing technique? Do you like this map?

Yours sincerely
Impractical Cartographer
