The original figure has decent paint work, but lacks certain sculpted details and some colors are incorrect.
I sculpted on the arm and leg bands, added the edging on the torso and wrinkles on the upper arms, and some bolts on the top. The figure was then given a complete repaint with lots of drybrushing and other weathering techniques.
The drill had some blood painted on it which didn't look bad, but it was too dull and flat for my liking.
I added a new layer of clear red on top of the already painted blood to give it a glossy look and some depth. I also sculpted a small dial gauge to add to the back pack, which was missing from the original figure.
The heels of the boots where missing the metal covers so those were sculpted on. Here you can also see the added detail of the metal weathering.
