Might be worth thinking of some variants for many of the "commoner" symbols too - if it really was hand-drawn, none would be the same, after all, so the option for a few variants would be useful.

So pretty, I hardly like to mention anything!

But as you asked...

1 & 7 - should they both be "Oberman", or is 7 actually "Obeman"?

Also, should the fields maybe have some kind of edging - fences, hedges, or even ditches - to keep the pedestrian herbivores out, and maybe some paths leading to them too. Those to the north seem a little detached currently.

I might be inclined to name the bridges as well, though that's probably just me 😁.

But one corner isn't curling-up where the glue hasn't stuck properly, unlike the real things 😉!

Depending on what line thickness you're using, you may get a better result drawing a separate arrowhead polygon and placing it on your line. The automated arrowhead lines can look pretty unappealing, because sometimes the line-end extends beyond the tip of the arrow, as if it's been blunted.

That's a shame, but you could still use it as a hex highlighter for key locations, much as the Ancient Realms and Modern Journeys styles do with circles.
