I think lighting and timing play the biggest roles in concert shots. Personally, I dont think daylight gives the best atmosphere, as the performers do not usually have the same lighting system on them as they do during an evening performance. I dont know how the song was going, but I think your timing was a little off in some which lost some of their appeal. If you look at most good concert shots, they are taken during a more powerful moment when the singer has the most definition in his/her face and body. If I hadn't seen the first 2 shots, I would have guessed it was a speech by the look of the 2nd 2.
Looking at the shots you were modeling after, you can see (as mentioned before) that there was a lighting setup that provided mood in addition to the lighting. Also, look at his face in the 2nd picture. All of those lines help give a feel for the movement of the song.
Of your shots, 2 displays the most emotion, but the lighting is just not there.
