Very cool.

This is the map of The Verse in Firefly, right?

You could maybe give the sun symbols glow effects in their respective colors. In the show, they worked with the scolors of the suns to show the difference between Planets in various systems.

You could make the anvil and the stum separate Symbols. Anvils are quite heavy, but sometimes they break, so having a spare in the corner on the ground is the smart thing to do

It may not be what was intended, or even wanted, but the first version of the hearth looks like a pool of slightly glowing miced meat to me...

The second version looks like hat hearth with coals. I have no idea if it is possible to give them some glow, that would make it even more convincing

Wonderful Idea, I love styles that fit well with other styles.

Most of what I would love to see is has already been mentioned (Marekt Stalls for the win!)

What I would like to see:

smaller Walls/Fences (maybe more of a drawingtool thing, that a symbol)

some vegetation other than trees

dead vegetation.

It looks really nice.

Some Eves are sinister, some are more like immortal hippies with a really strange cocktail of drugs in their blood
