The first was simply horrid, but that was mostly because the mesh (body shape) is defective and the skin wasn't very good to begin with.
So I scrapped that one and started over by making an unshaded skin by hand. Shading's uneven, way too dark on the front and a little too dark overall. You can't even see it on the pants.
I deleted the shading layer and tried again, shading the whole outfit at once so it'd be more even. Played around more with contrast & such to make it a little more subtle.
