I made the base myself. I cut out random sharp edges shape from styrofoam, stick them onto a wooden base layer by layer. I then mix cement with water and paint it over. A cheap brush is used to create the texture. The cement I use, should be from hardware store, found it in my storeroom :P
Too cool I love it! The base is really nice with building it did you use cement as in modeling plastic cement or the stuff you buy from the hard wear store? The general look and detailing of this piece is great. Good work...
