Render settings?

Specular is set a bit high and so is the bump, but I can't see that map. Reduce the spec value a bit and experiment with the highlight size. You may wish to create an alternate specular map or, at the very least, experiment a bit with the fine-tuning options available with various specular nodes rather than just relying on a single channel setting without the use of Poser's very nice nodes.

Take a look around for alternate specular node systems and the like. I'd bet my left foot, which I don't use much except for someplace to put a shoe, that you'll find several nifty specular threads around here or elsewhere.
