And what are the blue and green parts?
I thought of blue=puddles, green=gras (or maybe waste?) The blue parts are transparent so they look on snow terrain very bright (like ice or snow) and on dark terrain they look darker.
The waviness... yes it's a matter of taste. Maybe its too hard curved.
I found a graphics failure by this pattern. Look at the left picture. There you'll find some thin straight line "beside" the roads (best to see on top left road):
To examine this i've made pattern which has a straight green line only on one side of the road:
(open this in another window to see the whole pattern)
The right picture shows the result of this pattern: The green line is only on one side, but there is a "shadow" of this line on the other side of the road displayed. So the straight lines on the left picture are "shadows" from the opposit side.
@sirver: could this "shadow" be elimanted?
I've also made two different busy patterns (maybe for babarians):
Because normal roads are used to join buildings and first flag of building, they do not look great (at least for headquarters or buildings which are greater than small buildings). For babarians it's mostly ok, but the empire HQ looks really bad with a normal road in front of it. So some of these roads has to be edited too. I think the best way to do this is to edit the buildings and add there a piece of road to them. But this will result in greater images for the buildings... What do you think about that?
