Carving out, texturing and painting a ruined castle's courtyard out of a conviniently shaped polystirol piece. This thing ate away one week of my time and almost 70 ml of white paint. And, in the end, the result is far from what's intended. I really underestimated the surface, size and drying time, so there was simply no time for final finishing. There were supposed to be ivy, dust and decent sand and rubble... Sadly, there was no time to add those.
