I appreciate the comments.  With the lighting I was going for a sunset glow but I do see how it can be interpreted as a fire glow (wish I would've thought of it).  I do have shadows on but the 1st light is set high enough up that the shadows are not in the rendered area.  There is a 2nd light set in front of the women and set below foot level to counter the 1st light casting the women as blacked out silouette.  I believe I used aimed spot light for the 2nd light but I'm not sure about the 1st light off hand.  I just kept changing the light settings until I got a sorta warm glow.

I haven't messed with the default camera settings yet.  I don't have very many backdrops yet.  I had thought about moving the backdrop further out of finding some 3D trees to use instead.  I definetly rushed the background.

Originally the render are was set further back and much more of the scene was in view including the 'bad' guy the women is looking at.  I thought it didn't look right and you couldn't see her expression so I pulled the movie industry trick of tightening up the 'shot' to just the women and the chest in the foreground.  

With all these good comments I think I'll go back and tweak the picture and see if I can make it better.  I was disappointed by how her shield looks for one.  As for the clothes I worked on the scene with no clothes until I finally figured out what I was doing wrong, then I added them back. 
How do I make her skin look more 'real'?  I think that a more realistic skin texture may help as well.
