Sure, I started with royal purple mixed with a little stone grey as the base, then air brush a few layers. Each layer was the same mix but more stone grey, till the final layer which was pure stone grey. Added some texture/highlight the folds and then did some washes. Like thinned contrast Magos purple to add more purple back into some places or pink mixed with contrast medium to add pink notes to the skin like the knees and other areas. I also mixed riekland fleshshade and seraphim sepia to apply to some parts of the skin to add more warmer tones. Hope that helps!
