Hi Red
I'm thinking ...... The effect you are applying might be to much and maybe not all in the right places - see your image here - thinking too excessively applied

But here it is ultra realistic and at the right place! Also just the right amount of the effect to the left & right of the helmet.
You asked and I replied.
Now you also got the toning done like a master -100% spot on!

Don't know if the tire's rubber look like that without tinkering but that detail on them adds to the realism and the complete image looks REAL!
I like what you are doing and this last one is a favorite and maybe one of your best! VWD
