For the next few images, Same G2F, same skin, same Layton Hair, but different scene.  I started this exercise after watching a utube video by Jay featuring Colm Jackson talking about Rembrandt lighting.  That's what the above image was supposed to illustrate, but I mangled it completely cause I moved some of the lights around and adjusted the levels.  In the video, they are using Daz Studio with Iray,  and the results are awesome with the Render Studio light setup by Colm.   So after butchering my initial attempt, (the image above) using the Render Studio light set, I started fresh using Phil's Portrait Studio (Carrara content) instead.  This is what I came up with so far.
