Overall I think this is an awesome image. The percussionist looks devilish... captured the mood well for this shot... the slight problem would be the composition as mentioned, but then again, if you moved away to recompose you might not get the light and subject combination as you have captured in this image. Good one. I like it...
Yup, no energy. First impression was someone selling tea-tarik or a mama selling fresh hot milk in the early morning and not a drummer.
Focus was on the wrong spot (the metal stuff in foreground). Also maybe some motion blurr to create that energy. But I don't really know whether there is better way than this subject and moment to convey whatever your impressions you felt that night.
Though I agree that I didn't quite feel the energy. I did not know that the guy was a drummer, until closer inspection. Guess it all depends on the intent of our shot. Maybe you can tell us what you were trying to do?
I thought rules are meant to be broken ? So I wonder why everybody keeps on mentioning about where the subject is suppose to be here and in also in many other postings. May be I am not blessed with artistic talent to view the photo critically, hence the comment.
