so interesting because of the captured activity that, even if the viewer doesn't know the subjects, the picture is interesting to look at,
so beautiful that the anonymity doesn't count,
of interest only to the participants because there isn't anything of overwhelming interest and/or surpassing beauty.
Unfortunately these fall into the last category. They are fun or memorable for you and the subjects but the conditions under which they were taken really hurt the resultant quality.
Looking at just the first.
Shot at a slow shutterspeed and high iso (for that sensor) the result shows a lot of noise and some camera movement.
Those can be fixed to some extent but the overhead light makes shadows under his brows and highlights on the tops of his hands.
He is framed off to one side and it would be better if he was moved over a bit.
You can't really center him with the crop because then his hands just appear from the sides and look a bit disembodied.
With that camera you need a bit more light and you will get much better results.
