Great, a few suggestions, which IMHO would be usefull:
Amarr - Minmatar FW:
I would add Rens as in:
- Abudban - Rens - Rest of Heimatar
just because Rens is the major trade hub and a good hook to orient yourself from the normal maps to these.
Hek - Anher a note that these are just 4 jumps out of each other.
Ohide - Hati, same here 4 jumps through empire space.
Erkinen is a dead end pocket (AFAIK and in map v.3.52). I would note that this is a dead end or just put the whole dead end into it.
Due to Erkinen being a dead end I would not connect Gammel with Erkinen and write Rest of The Bleak lands as it might mislead to believing to a connection between Gammel and Erkinen
I would add Choonka to the Devoid region so you can draw the line from Choonka to kamela to Ohide and then rest of Devoid, likely as well note that if moving from kamela through choonka to Hati is just 3 jumps while it is 4 from Ohati.
Error@Ohati: You have a long line to Kamele and the out of region jump box to kamela attached to Ohati
Saidusairos to Egghelende are 6 jumps through Sing Laison
I would put Jel on the Map as well again as it is a Trade Hub and that via Jel to Saidusairos its 7 jumps.
Audaerne to Egghelende are 7 jumps through Sing Laison
Raravoss to Mahrikht are 11 jumps passing by Amarr.
I might have miscounted by a jump or so but this was just what I noticed first.
I would likely color the flags differently so you can better distinguish them from the Solarsystem name and thus from normal low sec regions.
I would also integrate these into the normal maps so when using the digital maps you can jump forth and back between the normal and the FW maps, as in use the links on the FW maps will keep you there but if you click on any "rest of region box" it will bring you to the normal maps.
A big thank you for all your work and Im looking forward to get my hands on the final once
