The above model is a Polish Suwalska Half-track APC from Brigade Models. I have spent years and lots of money buying bits to "chaos out" these generic looking models. It is only today that, completely by accident, I figured out the perfect thing to make the model more spiky: ordinary tack nails. I added eight ends of nails and two small links of chain. Now I only have to do that like 23 more times.
Still working on those Orks, I just had to do this because I was inspired by the shape of the nails. I want to finish these Orks before I move in two weeks or I might never finish.
