Get closer so that your subject occupies more of the frame. Use a wider aperture to get narrower depth of field so that your subject pops more relative to the fore and background. When possible and reasonable, control the light with... lights. Control in this context can be reflectors, strobes, snoots, gobos, flashlight, cardboard (blocking light from portions of your scene), whatever works. Try both natural and unusual lighting angles to get desired details to pop. Just be sure pay attention to color temperature of any lights you use.

If you're new to color correction and white balance, get yourself a calibration card. It can totally be a cheapie to start out. Hell, I still use cheapies. Protect it from UV light when not in use. Set the card in your scene at the beginning and end of your shoot. Those pics will make it easier to define baseline color corrections for your session.
