First up this is not my own work, I am psoting up a guidefrom battlebarge.com
for the benefit of everyone here, I have also mae attempts to cover use of citadels paints as well.
First basecoat the mini, black, then a dark brown if scars are present snakebit leather or scorched brown wouldwork fine here, then paint the skin avoiding the scar, eyes and mouth in tanned flesh till you get this.
Ral Partha Flesh was used in this step (You can sue dwarf flesh here). Paint the top of head, outside of ear, cheek bones, eyebrow, upper & lower eye lid, dots of paint at the rear of the eyes making crows feet, lips, forehead wrinkles, chin (optionally leaving the cleft dark), cheeks down to and including the jawline leaving basecoat color underneath the cheekbone, tip of the nose up halfway, bridge of the nose down halfway leaving a space of the base coat in the middle of the nose and a space of the base coat between the eyebrows and the bridge of the nose, nostrils leaving the base coat between the nostrils and the tip of the nose.
To make the model look younger omit the dark lines in areas with the crows feet, the forehead wrinkles, and the middle of the nose.
Magic Wand Dragon Colour White Flesh (I would use a mix of skull white and dawrf flesh to achieve the lighter tone) was used in the step (out of production). Dot or fineline the following locations: top of ear, earlobe, crowsfeet, very top of cheek bone, eyebrow, bridge of nose, tip of nose, nostrils, edge of top of lip leaving a gap directly under nose, bottom lip, jawline, both sides of chin, and random lines on the top of the head (painters touch).
Vallejo Model Color Ivory (#005) (Use skull white)was used in this step. Eyes are two dots in the corner of the eyes, leaving black all the way around. Teeth are a line inside the mouth. Depending on the model, the bottom teeth might not be visible.
Hope this helps everyone!
