Bush? All of our houses have shrubery. Adjacent to us is the Mentor marshes, which is all tall grass. DON'T GO IN THE TALL GRASS! AHHH. (Jurrasic park). Bout every 3 years, someone will light it on fire, and its many acres so it will burn for days and days. I think the city likes it; we get a lot of publicity while the marsh is on fire. Heh.
Wow, that terrain is really two dimensional. You need to use the raise/lower tool more, and add some height changes. Its also barren, nees some doodads. Trees, shrubs and bushes, maybe a couple flowers. Weeds and petty flowers often grow at the edges of the road. Nice boulder here and there would be nice too.
LOL - Would you believe there was a picture on the internet? here, for your viewing pleasure.
