Your art is incredible, especially for someone who has (relatively speaking) "just started out".
Not a criticism, but I noticed that image of Quinn lighting her cigarette suffers from the well-known "black rings in the eyes" Daz/iRay issue. Not sure if you know this but it can be fairly easily solved either by using a Cornea/Eyemoisture Scaling Morph (I think, I usually use the one which can be freely found here:

), or by switching the "Render Settings -> Optimization -> Instancing Optimization" to Speed (think it's Speed, otherwise you should try Memory, it's one of the two).
Anyways, Keep it up! And, I'm already looking forward to seeing more of your art in the future!
