There can be few (tasteful) figures with more flesh than Thrud. I've had him partially painted since I bought him new. That's a while ago now...
The six paints appear to be grouped into two groups of three, with a dark, mid and light tone for each. I used five of the six in this chap, with a fair bit of mixing.
The paints have a nice creamy consistency compared to the thicker Scale 75 paints that I usually use and they're not as light-suckingly matt as Scale 75. They thin well with plain water and the coverage is good over black. I haven't used Vallejo much so I can't really compare those.
They're nice enough, and I'll probably buy more, but I prefer Scale 75.
