Very nice. What colors did you use for the skin and hair? These guys look Mediterranean. I seem to only be able to paint up Swedish looking guys. I would like to be able to make skin tones like yours.
i also love the faces, perhaps some deeper shading in the eyes would do it some needed work. Also, when working with purples, remember that if it's the spot colour (ie. the main contrasting coior) use a red based purple, grey purples dont go well with other nuetral colors. other than that nice work
