Rejected 60% photo

1327 harsh light & shadows.  Try using diffused light instead of flash.

The first one is missing blacks:

The second is also overexposed and is missing contrast.

And the last one too.

The two last pictures have also framing errors.

I like your images which are crisp, simple and nicely composed. I've been searching for flaws, and they're not very obvious. In the first image, I agree with @ElkinsEye that the mottled texture of the background could be confused for noise. I also don't think that the color of the background complements the subject, but that's an asthetic opinion that wouldn't necessarily be reason for a technical rejection. Applying just a bit of noise reduction in LRC reduces the effect. There's also a small spot on debris on the left side on the white tabletop. I suggested re-editing and resubmitting, and that's a very simple edit you could do to justify re-uploading the image. Note that if you resubmit the exact same image after it has already been rejected, Adobe can conclude that you're spamming the database and lock your account. 

The second image is a bit overexposed, by about 1/2 stop.

The third image is also a bit overexposed, by about 1/3rd stop. It's unfortunate that you cut off the wooden man's arm.

All of these could re-edited and re-submitted and would most likely be accepted in my opinion.

I would suggest uploading only a few at a time, wait for feedback, re-edit and re-submit if possible, then move on to the next small batch. A slow and steady approach has worked well for me and helped me to learn from my mistakes. Quite a few of my re-edited and resubmitted images have been accepted.

In the first one perhaps the texture on the brown wall was mistaken for noise. Perhaps if you smoothed that out it would be accepted. For the other 2 they look fine and I have no idea. It is almost like once a reviewer rejects an image it contaminates the whole lot. I just had 20 rejected that were of many different subjects taken with different cameras years apart. All are tack sharp and properly exposed. Frustrating!
