Yes they are over powered by the HDRI IBL light, try to set the body diffuse color to Red: 127 Green : 127 and Blue : 127  intensity to 120 , that will create the balance for the surface don't worry it will not affect the body textures colors...if this works for you then change the diffuse color of the all elements you use in this render to the above and nothing will be over exposed no more, the shadows works always perfect with the HDR IBL so you should get a great effect.
