I spent my first 18 years in Clarksdale. It was certainly 'juke joint' area. I was surprised at the tourism caused by the 4 or 5 yearly festivals. It's been 40 years since I sat in one of the clubs there. I did get to see Howling Wolf one weekend in a club less than a mile from my home. As far as the portraits: they look good, I'm not familiar with any and as one said, legends is debatable. Maybe they are in the local sense.
Eyes not central. I don't mean in center of image.
Which set of eyes do I look at?
The bright mouth area distracts from eyes.
