My admiration for Tolkien's map-making skills has been greatly enhanced by my own efforts to make maps of Beleriand. It's way harder than it looks!
I've made two attempts now: This is the first one, for
chapter 8 of Quenta Narquelion (my Ghost Feanor story)
And this is a War of Wrath map for
Chapter 12: In Armour of the Elder Days.
(Yes, I know I've missed the 'g' in Angband! I can't see a non-obvious way to fix it and I can't bear to re-draw it, so it's staying like that. Digital mapmaking would be SO much easier.)
