That came out very, very well.  As you become more familiar with the node arrangement, be aware that the generic VSS and the Apollo VSS are quite different.  The Apollo VSS has been optimized, the only change that needs to be addressed is the background color in the Image_Map.  That should be changed to white to accommendate skin textures from other sets.  BB's tutorial outlines the nodes you would commonly adjust to change skin tones, AO, etc.
