if you take this into Photoshop (etc.) and apply just a touch of diffuse glow you can increase the effect, with control. If you don't have PS, i think other 2d editors have Difuse Glow.

If I were going for this look I would take the top version in; its shadows are darker, but that can be adjusted. Meanwhile the contrast between light and dark on the top render means that manipulating in post you will have more options.

The bottom render is "softer", yes, but flatter, too. I guess I am saying you want the depth that comes from contrast but also with the ability to apply softening overall.

Are you in PoserPro? If so, you may wish to try rendering out to openEXR format and attack it in PS with gamma, exposure, lightness settings in 32-bit mode.
