Folk-singer portrait-What more needed?

There is a reason posting this image for which it is a bit weak image....Cud u think? The guy is a folk singer at a tourist place. As happens, we generally move with our cameras without switching on inbuilt flash or where the hot-shoe is there, we avoid fixing on camera flash....May be other people's attention is distracted??..Here,.the eyes look dull without a sparkle....In faces, the eyes are the main force to depict a picture. Had I used an oncamera flash, I cud be able to reduce some harsh shadows on face also....So technically, it is not a perfect picture, as I feel...and let u know..
