It looks pretty good.  My only concern is that the shader is emitting quite a lot of light.  You have an active Ambient channel which can be eliminated; it doesn't contribute to the overall effect.  However, you are combining Diffuse and Alternate_Diffuse channels which will make the dress glow.  Under average lighting, you might not see any problems, but darken the scene and the dress will 'light up'.  The Soecular_value channel is very high, 5000%!  This is unusual, but this hack will have to do in the meantime.
