Rejected for Technical Issues

Ask yourself what is the market for the first and last photos.

I believe depth of field is the most apparent flaw.  The depth of field is so shallow that I'm seeing very little in focus in these when viewing at 100% in Lightroom.

Out of focus, mainly, for all 3 pictures.

The first one also exposes chromatic aberration:

and noise.

The second one has a high noise level and also chromatic aberration…

For all pictures, I see little commercial appeal!
