Just a note - the arms are magnetized so that they can swivel or even come off when smaller minis are crowded around them. It's not the first time I've seen magnets on a mini, but they work especially well for this particular model.
The rust patches on the model were created by basing the model brown and then sprinkling bits of rock on it. A green coat of paint was put over the model and then the rock salt was scraped off, leaving the brown exposed.
But here's the piece's awesome sauce...Nick cut off the foot of the colossal at an angle so that it looks like it's rising out of the water that he constructed. Now, it looks like the Galleon is rising up out of the ocean. I love how the water effect overlaps onto the rim of the base, too. Very evocative.
All for now.
