Well, onto the techniques used here. I wanted the feet to look really worn, rusted metal and flaking paint at the bottom and more grease and rust further up. After a base spray of black i painted the bottom of the foot black and added some brown, red brown and orange paint in some random patched to give some depth. After this I dry-brushed on several layers of different color metals, also with some random coverage. This was followed by some inks and washes before a last dry-brush. Once this stage was done I used masking tejp to make some random patterns along the bottom of the foot and toes. The edges were then covered with the base paint I am using for the titan to give a lighter layer between the metal and the paint. After this I used my standard Northern Ghost green recipe on the bottom of the foot and toes. After drying I removed the tejp to reveal the metal beneath. Sadly some of the paint came of with the tejp so I had to do some minor touch ups. Over all I am pleased with the effect even if it could be more visible, the metal and the dark green paint blend together some what. We will see what happens one I get to the weathering stage.
When prepping the model I noticed that the thigh is actually not just a solid piece but is actually consisting of two parts (cast as one), and there seams to be a dampening system in place. Initially I had only planed to paint the parts below the knee in the base paint but now I decided to go all the way up mid thigh to the joint. There is a risk that it will look like the titan is wearing shorts but I think that with the armor plating in place and some weathering it will look alright.
So far I have painted one leg up to pre-weather and just started on the other. I will paint both before starting with weathering and chipping to keep it coherent. This will take some time as the legs are huge and my painting style is very slow. I have to break each leg into several areas (5) that are painted separately. Each area then sees nine layers of paint just to get it to this stage, so I am expecting the painting of this beast to take up to a year or so depending on how focused I can stay.
Once the legs are done I will fix the pelvis and the pistons there and once that is assembled I will attach everything to the base before gluing in the rest of the things. I hope that it will work out ok.
