This is actually a rather well-sculpted piece of an older Adam (as contrasted with the "newly born" Adam in the Mordenheim's Laboratory set), standing on what might be a rocky outcrop on the Isle of Agony. At his feet is a bag with a suggestive outline of a small human figure (young Eva?). He has a raw-boned, muscular look with raised scars or veins on his skin.
There are a couple of schools of thought on what color one should use to prime a mini for painting: white keeps colors nice and bright, while black can provide instant deep shading. Usually, I prefer white unless a figure (like Soth) is mostly going to end up black; light colors and fleshtones occasionally suffer from the black bleeding through and affecting the color, and it's often easier to paint black over a light color than get enough coverage with lighter colors to conceal the black.
Here, though, I deliberately used the bleed-through property to give a darker, dingier skintone to Adam, as well as using yellow ink as a glaze over my bloodless/undead skintones to give him a jaundiced look similar to his inspiration: Shelley's nameless monster in Frankenstein. Small amounts of pinker colors were used to highlight the scars.
