one thing I see with a lot of users on here, is that they tend to use lighting that mimics light bulbs and stuff, but that doesn't usually turn out well. Often having to use ghost lights to properly support the shot (which isn't bad, if anything that is expected and very standard). unlike many, it looks like your render at least has plenty of light, but I do see what you mean, the background looks too well lit while the character perhaps could use more.
My only guess is it is due to most everything being white, meanwhile character skin textures I noticed tend to be darker than what I typically use (at least when I port over the skin to blender, I don't know how daz shaders handle the skin differently).
two things you could do is either lower the whiteness of the object, this probably isn't best. If anything, after throwing the image into gimp and testing, I would say lower the camera's exposure to prevent washout, and I would say adjust the gamma so the contast is the same (lower exposure, darker image, lower gamma the more contrast but whites pop out), but I myself prefer higher contrast so I probably wouldn't need to tweak the gamma after lowering the exposure.
Then there is always the question of: is your monitor color calibrated, as that will always impact your work flow.
also this may help, I thought it was some pretty good information
