Thanks guys! I didnt use anything fancy. I used acrylic paints, small model brushes and a sponge. I basically mixed white with tamiya dark yellow for the base colour. I applied this to the body with a brush, and used a sponge for the arms and legs. I then mixed black with tamiya nato green for the darker spots. I added more green for the lighter areas. I then used terracotta colour for the chest and obliques finished with a simple red for the highlights.
