Might want to clean up the handle of the halberd, highlight the robes & apply a wash of Nuln Oil/Badab Black to the chainmail part :) Also, her lips look a bit too bright to me, although good job on actually picking up a detail that small. The platemail looks good, especially on the hands!
Also, try something like this for photographing: http://strobist.blogspot.fi/2006/07/how-to-diy-10-macro-photo-studio.html. Does wonders!
