After a quick look, I would start with decreasing diffuse to 0.9 (1.0 diffuse does not
occure in nature, well at least in normal materials).

Maybe You would also try for example following radiosity settings:



#local QQ_RAD = 4; // <===== set this variable 0,1,2,3,4,5,6 or 7


#declare CFG_AMB = 0.3; // <==== set this variable for ambient when NOT using
radiosity

global_settings {      
  max_trace_level 20  
  
  assumed_gamma 1.4
  //assumed_gamma 2
  
  
  #if (QQ_RAD)           
    #declare CFG_AMB = 0;
    radiosity {  
      brightness 1  gray_threshold 0  max_sample 10 // <-- !
      #if (QQ_RAD=1) 
        normal on  pretrace_start 1/48  pretrace_end 1/256
        count 30  error_bound 0.90  low_error_factor 0.75
        adc_bailout 1/60  recursion_limit 3 minimum_reuse 1/96  nearest_count 5
      #end  
      #if (QQ_RAD=2) 
        normal on  pretrace_start 1/48  pretrace_end 1/256
        count 50  error_bound 0.80  low_error_factor 0.70
        adc_bailout 1/60  recursion_limit 4 minimum_reuse 1/96  nearest_count 6
      #end  
      #if (QQ_RAD=3) 
        normal on  pretrace_start 1/48  pretrace_end 1/256
        count 80  error_bound 0.60  low_error_factor 0.80
        adc_bailout 1/60  recursion_limit 4 minimum_reuse 1/96  nearest_count 6
      #end  
      #if (QQ_RAD=4) 
        normal on  pretrace_start 1/48  pretrace_end 1/256
        count 100  error_bound 0.50  low_error_factor 0.80
        adc_bailout 1/64  recursion_limit 4 minimum_reuse 1/256  nearest_count 7
      #end  
      #if (QQ_RAD=5)
        normal on  pretrace_start 1/64  pretrace_end 1/256
        count 200  error_bound 0.30  low_error_factor 0.80
        adc_bailout 1/64  recursion_limit 5 minimum_reuse 1/256  nearest_count 8
      #end  
      #if (QQ_RAD=6)
        normal on  pretrace_start 1/64  pretrace_end 1/256
        count 500  error_bound 0.23  low_error_factor 0.85
        adc_bailout 1/75  recursion_limit 6 minimum_reuse 1/256  nearest_count 8
      #end  
      #if (QQ_RAD=7)
        normal on  pretrace_start 1/64  pretrace_end 1/256
        count 1000  error_bound 0.17  low_error_factor 0.80
        adc_bailout 1/80  recursion_limit 7 minimum_reuse 1/256  nearest_count 10
      #end  
    }
  #end
}
default { 
  finish { ambient CFG_AMB } 
  pigment { rgb 1 }
}
