Looks overprocessed to me, maybe just sharpening, but the back of the salt shaker is shoing some weird anomolies. The two tannish yellowish corners should be cut out of the shot.
The size of your image is way below the allowed 640 pixel and 150 MB limits. You should take advantage of the size allowed. The compression here has ruined an otherwise decent shot. There are tutorials for resizing your image in the "Learn" section of the top navigation bar. Good luck with your future challenges, keep shooting!
Not very well executed. An actual shoulder in the photo might have given it more life. There was an entry using this superstition in the last Superstions challenge that placed in the top 5. Have a look at that one to see how effective it could have been.
As for your choice, you could have cropped closer - those top corners are very distracting. Also, the focus doesn't seem quite spot on. And there are some compression artifacts in the image. Maybe you didn't resize it properly? Or maybe the resolution of the camera was too low.
Nice idea, but I'd prefer to see the salt in better definition - since there is very little to look at in the picture, what there is needs to be attention-grabbing. Unfortunately the salt looks like a white blob mostly, with grainy bits around the edges.
I don't care for this at all, the yellow in the upper corners is a distracting, your reflection in the top is a distractent, the over blown salt is a distractant. Image just doesn't work. a tighter crop, better lighting, differnt background...
I like the idea and execution is pretty good, but ... the yellow in the top corners is very distracting and really doesn't seem to add anything compositionally. Also seems like maybe it's a bit oversharpened or something.
