Well, finished!
This has been one hell of a difficult thing to paint though. It first came out too orange, and then too grey, then I switched to oils, didn't like the result so soaked the whole model in dettol and cellulose thinners. Then, had a final go and it all clicked.
This is the first attempt. The face looks good, but as I said, a bit too orange
The second one lost too much tone/colour. I don't think it helped that this model was primed grey - kept the colours a bit too muddy
This is just meh. I needed more definition on the skin texture
So here is the final model! Started with no primer, straight into flesh tones with the airbrush, slowly worked up the browns. Then, I drybrushed the entire model with a much lighter colour, and then washed over the drybrushing to help it settle a bit. As I was afraid of ruining the model near the final stages I switched from using acrylics to using gouache paint (water-based poster paint). This meant that if I overdid anything I could reactivate the gouache with water and remove it without ruining the acrylic paint underneath.
Luke didn't turn out too bad - made him a new set of clothes so he looks dapper.
This lighting is quite harsh - it is a bit more subtle than this, but as you can see, it really brings out the detail. The eyes were done with silver paint with a gloss varnish. Teeth and finger/toenails were also varnished
The base was surprisingly effective. I mixed sand with white interior filler. The filler binds the sand perfectly, lightens it up to match the film, and prevents that fake glass you see when sand is mixed with PVA/white glue. Bones and stuff were made with sculpey and then washed over with brown.
I was debating whether to give the entire model a gloss varnish, but I usually find that it can very quickly make models look like toffee apples. In the end I mixed some brush-on gloss with a good amount of white spirit, and put it into a spray bottle. I then very carefully spritzed the model, being damn careful not to go overboard! I like the effect as it is subtle and hit and miss.
So, that's it! Hope you all like it and thanks for all of your continuing encouragement. I'm finally happy with how it has turned out. I'm still sourcing someone to make casts of this model, but as soon as I get something sorted I will post on here and also create an interest thread linked to this.
