I agree with BB, some of those combinations are suspicious and do not amount to anything positive for the render.  I ran several renders based on this node combination and have not been successful in duplicating the oddity.  I have noticed that specular response is driven through the roof from what I attribute to the blinn and glossy node combination into alt_spec.  And the velvet node is desaturating the color in the red of the cape.  This almost looks like damage control for bad node combos. 

I am suspicious of the reflection map which really isn't necessary under IDL conditions.  My test scene only consists of BB envsphere and 1 infinite light.  How was this scene composed and ultimately rendered?
