Thanks torilen! Yes thats what I heard too thats why I used just normal black acrylic paint as a first coat without primer. It looks like it worked, I hope it stays on.

There are different types of styrofoam, the one that is made of little bubbles (when you break it apart) and the one I used which is XPS styrofoam. Get XPS, thats what terrain crafters use, cause you can just easily cut ino it, and it looks good.
And thanks whitebeard! That tip with the asphalt texture is great, also finding a piece and using it to carve it is a great tip! I used this little stonetextured miniature ball and rolled it on the surface a few times. Crafting is really fun, it sparks my creative thinking. I have all these ideas of what I wanna make all of a sudden!

:D I want to create hazards and stone and rock formations next, so I can use it with the board. I saw somewhere online that some people use sprayfoam to build rocks and such, I gotta check into this! Fun projects!
