1st rubble pile, but even more so with this one. Again, the base is an old CD, with various pieces of polystyrene, Airfix kit bits, sprue offcuts, a thread dowel, pen nib, & other detritus incorporated as junk. I also used sliced-up parts of an original Necromunda bulkhead, & as grille flooring: the disposable 'rafts' left-over from 3D-printing projects. The polystyrene chunk that dominates this piece has a nifty warning sign & arrow that I thought would look good when painted.
I really enjoy making free-form scenery pieces like this, as pretty much anything goes. Once you've picked a few parts, they seem to fall together into a logical arrangement with very little effort, & almost take on a character. I think this 2nd pile of rubble is more interesting & successful than my first one, which was more a vertical stack. This one has more interesting angles, more variation in texture, & more contrast between rusted metal & plascrete. The big pile of grit also adds more realism than blocks alone.
