Project Update ...
I've weathered the wall by gently scrubbing in some pastels (a mix of buff, light tan, and light gray). Now it looks slightly scuffed, as if blasted by lots of sand and desert winds. I made a sandal out of apoxie sculp last night, which I'll paint tonight and affix to the groundwork (sole facing up as if left as an "insult" to the character in the portrait). I've also added 4 spent shell casings behind the GI. I rolled out a thin sheet of apoxie sculp last night, which I'm going to break up & paint to simulate shattered pieces of tile.
It was also suggested to add some trash, such as paper, strewn about. A friend of mine - Paul Kelly - shared with me a method involving tissue paper and a wash of white glue & water. Anybody else got a good method for simulating strewn trash?
