High-Detail Fantasy TTRPG Maps

I'm seeking an artist to create a series of hand-drawn, high-detail maps for a TTRPG. This includes a world map, five regional maps, and a couple of city maps. Will have additional projects for more regional and city maps a bit later. I have some digital images as concepts to work from (three examples included).

Requirements:
- Fantasy art style
- Highly detailed with intricate designs
- Include geographical features (mountains, rivers, forests), man-made structures (cities, roads, castles), and mystical elements (enchanted forests, dragon lairs, magical locations)

Ideal skills and experience:
- Strong portfolio in fantasy hand-drawn maps
- Experience with high-detail cartography
- Ability to create both physical and digitized map assets

Please provide samples of previous work and estimated timelines.
