First up John, I like the background treatment.
The
model - hmmmm! The problem with using gold is the differential in the quality of reflective light. From the waist up the effect is good. From the waist down, and due to lighting, we see a degradation in the gold reflectivity, going from gold to what appears to be dark brown.
The right leg is in a very awkward position and the last time I saw that kind of pose it was the result of a truck hitting someone. I also find the lighting differential on the right and left arms distracting coupled with a lack of detail in the hair falling over the right arm. Maybe the hair should have fallen behind the arm.
