The render in #2 - could it be, that the orange peel effect is due to the bump map? It looks to be a lower resolution on the body and the strength is at least twice what it should be. The head neck texture join is there because the density of the pixels on the Head is higher than on the Body? Adjustment of the relative texture sizes can minimize this, but the same effect at wrist and ankle is unchangable - because the hands and feet are on the same texture as the rest of the body.
