That first image is exhibiting fireflies in the render.  Are you using an HDR image in the background for any lighting?  If so, check the Gamma on the image, it needs to be set to 1, not 2.2.  Also, you may need to render at a higher pixel value.  In your case, 10 is not enough.  I have seen other users push the values up as high as 50 or more. 

For the second render, the skin shaders are off for Superfly.  You would really need to convert the textures to Cycles, either using the PhysicalSurface or Cycles root nodes.  The better option with the Cycles node is to combine it with the PrincipledBSDF and optimize those shaders for Superfly rendering.  Keep in mind, skin shaders coming from the same vendor do not mean that they follow the same formula with every character they develop.  Chances are that nodes may be rearranged, changed, or completely reworked to accommodate specific displacements, specularity, etc for the skin's response to its lighting environment.
