For the thekoncept : I work with oils, and blend them together wet on wet, making sure I get a soft transition.
The day after I look if it's needed to give a little extra highlights and some extra detail. The metals are done with printersinks, and the snow comes as a white pouder in a little package (which I purchased years ago) but you can buy it in about all webstores for figures now. I mix it with a little water and some woodglue.
The step by step of painting a bust can be seen on my blog, first page on the right side, where a little man is pointing down. That's about it, I suppose.
