You missed some hair at the back of the head, and the edge of his shoulder is blurry...

Agrees with CMYK but the image being so close should be more in focus like the barber and customer, since they are so close to distance. I understand good source is sometimes hard to find but maybe this wasn't your best choice for outside source. There are way to sharpen soft images like this and perhaps someone else can suggest a method to improve the sharpness, but it will be minimal improvment.

CMYK: Thanks....Have made changes....
