Barts points are excellent.
I agree about the close cropping and feel I must sound like a broken record. My impression is that the mantra of "frame closely and crop even closer" or words to that effect, often is poor advice as art is a bargaining between many ideas in the mind and the developing art that you are creating engraved in light, dark, colors and even texture or the feeling of these.
I feel it is performance art and limited in progession when one just snaps an image and thinks it's over. So I think one should err on the wide side and get more of the milieu of the subject that captures your heart, the beginning of the romance that makes art, from the best positon and lighting, for these are the foundations of the photographic picture. The deciding work, however is in the wet or digital darkroom. Here the cropping, further exclusions and a myriad of choice have to be made and makes the imprint which will either leave the picture ordinary or perhaps once in a while yield an outstanding photograph.
To have robbed oneself of the choices of refined thoughtful bargained composition becasue the subject was already framed too tightly is, in my opinion, a mistake. In work for a client, tighter work may be a necessity of workflow and time allocatable. However, for full expression for artwork, I would be mopre generous knowing one can reaffirm one's impulsive decisions or else modify them.
To extend this further, it's necessary to sometimes present one picture on its own, even at time with a special frame to isolate it from the page and create the correct background from which each photograph can be observed, enjoyed and even understood as you might intend or according to the viewers own unique perception.
Your pictures deserve handling one at a time. So, if you might agree, presenting one of them and getting discussion might do better justice to your work.
There is no need to do what I suggest if you think your pictures all belong together. But where they might be separated to advantage, I'd wager we'd do better.
