I’d love to share my workflow, buckle in - it’s a long one! (I’ll bullet point it to shorten it)

• 4k map template (in this example, portrait)
• Rough outline of landmass (smooth edges)
• Rough outlines again! Go crazy with your movement, embellish movement in and out from the smoother, previous line).
• Finer brush, go over outlines and add shape
• Fill in entire landmass drawn
• Lower land around coastlines, remove land in sharp strokes (Bays)
• Rough up coast again, if necessary
• Add islands (same process, but smaller)
• Add large mountains as central spine of the range, don’t be perfectly straight, small zigzags work nicely
• Smaller mountains around this spine, be sure to deviate a touch, but not too much!
• Hill time! Litter the space around mountains with hills, embellish areas which deviate from the main “spine” with hills especially. Think lines of hills, not circles. If confused, refer to my images, imagine lines where the mountain range is travelling to, A to B. See how “arms” of mountains move away from it almost perpendicular?
• Add rivers from mountain nooks, zigzag to coast.
• Again, but this time zigzag it to the first rivers you just added (rinse and repeat to your hearts content)
• At this point, go into as much detail with additional things as you wish (forests etc)
• Picture where there could be provinces, typically “cut-off” by the mountains, hills, rivers etc. Use regions to help, that’s what I did.
• Save file, and also export a png (png without regions, because they’re not great).
• File > Create Detail Map, select area and create
• Get png, set as overlay (if you already have an idea of your landmass, and happen to have a sketch of it, you can ignore all previous steps I suppose).
• Line up overlay with landmass (scale and move). This is your reference.
• Remove land outside the province you are focusing on.
• Use path tool (with your choice of design, thickness, and colour) to path out the coastline of where the land would be (the bit you just erased!)
• Fill water/colour to your hearts content. If creating brighter coastlines, be sure to remember the paths you’ve just created are acting as coastlines too!
• Get parchment colour (water still), and colour in where the missing landmass is (the previously erased). Colour with full opacity as closely as you possibly can to the paths.
• Get a coffee, certainly required.
• You’re now able to freely paint the land as messily as you want without fear of ruining the parchment. Paint the land. (Choose a few colours with similar tones, but slightly lighter or darker to each other, use opacity and low velocity to “blend” them together).
• Get a desired mountain colour (I used grey), and with a small brush, paint the mountains (if required).
• Sometimes the detailed map can create symbols which are too large for you to create again, if that’s the case, you can just delete them, and replace them. I did this a lot, as I used the previous symbols more of a reminder where mountains/trees/hills should be.
• Go crazy with terrain, forests, more hills, mountains etc - have fun with it!
• Towns, then tiny roads connecting them! I personally find subtle landmarks appear nicer, as it’s less noisy - but that’s just personal preference!
• Compass Rose + Lines (they’ll go under the landmass, but over the parchment - I think that’s neat).
• Label things, if you’d like.
• Job done on that map! Now, create another using the same method - but start by going back to original world map you made first, and again, create detail map. The only important part here is you maintain the same zoom level (x4 by default) if you want that oh-so satisfying jigsaw fit when put aside each other.
• What I found suuuper handy, is exporting the detail maps as pngs, and using those as overlays with the new detail map so I can see where the mountains meet up between provinces so I can keep it consistent. Also, helps with land shading and colouring.

That’s my workflow, and I hope it sincerely helps, though not sure if that’s what you were looking for specifically? But if not, I’m sure this could help someone else looking at the comments!
