To start off with it depends a lot on the image you start with -- careful lighting at the stage of taking a picture makes a big difference.
One general approach is to use an Overlay layer to enhance contrast and lighting. ByRo's
action and his associated
tutorial are a good place to start, or you could just add an Overlay layer filled with 50% gray and use a very low opacity (around 5%) very soft brush to brush on in black to darken or white to lighten. In the example below, which is just a very quick 5-minute initial attempt to illustrate a possible approach, I've used several layers generated by ByRo's action and then tweaked with an additional Overlay layer and some brushing by hand on top.
Then something like a Gaussian blurred layer, possibly in Screen mode, with lowered opacity and a layer mask added so that detail doesn't get obscured, will help get the kind of texture you are after. In the example below after I'd adjusted contrast and flattened I duplicated the background, ran Gaussian Blur, changed the blending mode to Screen, added a Hide All layer mask and then brushed onto the mask in white where there was skin texture I wanted to soften.
So far as the colour goes I suspect that wall was pretty blue to start with -- but you can tweak by, for example, adding a Hue/Saturation adjustment layer and selecting that you want adjustments to apply to the blues only (for added specificity, you can sample from the original). Just as an example, I've used that technique here to boost the colour of her straps. But, again, it depends on the original image -- there might be more appropriate techniques.
