I love the effect. Since I'm experimenting with calligraphic maps (and having an hard time by the way) I think I'll give it a try! :)
I should actually upload them and give them away ... though they're not as nice as Black Cross's (Schwartzkreuz)
The overall effect is cool, perhaps it just needs a bit of variation. And traits are light, which means they can be colored more easily.
You have my vote! :D
