I primed the whole costume with a dark grey. For a more realistic "stone look" i finished it here and there with some brown and light grey colors.
Step 5: Entrance
Here you can see the backside of the costume. This small "triangle" is where you get inside after opening the zippers. Because of the small size of the "door" it is necessary to "bend" the whole costume. This is the reason why you sholudn`t connect the foam pieces whith each other, only connect them with the painter suit, otherwise the costume isn`t flexible enough to get inside.
