So today I've finished spraying up the armour of Joe. I spayed over the original base with transparent red and green the a metallic purple/blue.I then shaded with smoke and finally adding a lighter tone of the purple on top.
I then shaded the armour with pastels.
I blocked in the jacket, based the visor, badge and belt.
GW do a nice new wash called Nun Oil which I will use the highlight the joints.
