Why not just create a map, in a similar way to that of a specular map, but for subsurface scattering?
That way the SSS shading would only be applied to the parts you want it to be applied to leaving the rest to have a less washed out look.
Phew, this is practically making me sick with how bad I am at sculpting. :o Terrific job on the modeling and texturing! The lighting is alright, but I would like a little more light overall so I can see all the great detail and such. Particularly around his eye—I always like a slight glow on creature eyes. =)
