The marine as he stands now... green, yellow and black are mostly done, but I have a fair bit to do on his cloak. I am unhappy with the way is coming on and have tried numerous colour combinations and am now thinking the whole cloak needs to be covered in scales (or at very least smoothed right out as what I was hoping to look like a rough leathery texture has ended up just looking messy...)

I still need to work on the gold - I've bought some alcohol based Vallejo metallic paints which should be nice and bright with a real shine to them. I'll break out the inks to try and keep them glossy and hopefully increase the contrast between the metals and the surrounding colours.
