cool shot. i have a couple of suggestions that i hope can help.
if you have a lot of light and dark areas i'd use that to your advantage. i like that area around her hands knees and feet. lots of cool shadows and lines. that could be a cool contrasty picture if taken on it's own. mabey just on of the hands. then accentuate that cantrast. if you want the whole image, i'd just under expose it. then your whits wont blow. and you'd get a crisper image. again, focus on the darker mood with lots of shadows. or if you want, PP with Image, Adjustments, Shadows/Highlights and then remove some shadows. that way your highlights wont be blown.
as it is i like the lighting of the scene. it would be fun to shoot. you live near by? if so play around with it. i like it a lot.
