Back to our Space Marine Statue of Matt Black: Former hero of the Imperium, noted for his valiant efforts against the Orks on Taurshaln (I don't know any of the actual worlds where Orks invaded). Eventually succumbed to spore poisoning, and is now believed to be known as Dok Graftbitz. Thanks C'nor (Outermost_Toe) for that history lesson.
So, having finished off his Red Planet based plinth I used my new found friend Tin Bitz as a metallic basecoat. Whatever level of verdigris I'm going to put on there will be some level of transparency which will show through this metallic colour.
Now I may have missed a few steps here [you don't say] but I think I did quite a thin mix of my Anita's Acrylic Turquoise and some black then some light overbrushing with the Turquoise and then mixing a bit of white into it for a second set of streaks. This paint has a very matt finish, it tends to have good opacity but if 'worked' a little bit with the brush can have areas of transparency and areas of opacity. It's why it worked so well on the 'nids in that you are never going to get areas of 'flat' colour in the natural patination of the 'nids.
The verdigris is also natural in that it weathers over time so this mix of transparency levels works and the great thing is that as it naturally streaks you can get away with all sorts of levels of brushwork. Once I added in some stain streaks using Devlan Mud it started to really come alive. The whole model is incredibly matt and dry to the touch, not sure if that has anything to do with the black poster paint basecoat but it really has the feel of some of the heavily corroded verdigris I've had the chance to observe recently.
All that's left now is to paint the skull on the plinth, add some more highlights to Matt Black and touch up the Devlan Mud stains but I'm really pleased with it. It may not be perfect and it may not quite follow the tutorial that I used as reference but I reached a point I'm happy with using the skills I have to do something different but not a million miles away from my what I usually do.
