I just realized I left a signature on at least one of them - Like I said, I'm new 😛
Nice ideas. Most of your photos are underexposed and poorly focused. Not enough depth of field. Also the impurities in the backgrounds or black empty space needs to be removed. Your signature is not allowed. Some of the screws have overexposed highlights.
Thanks for the feedback
I don't see much commercial value in the abstract balls. And cropping too tight or clipping images hurts it more than helps it from a sales standpoint. If customers wish to crop or clip later they can after they purchase.
Meanwhile, read these links for more tips.
Hope that helps.
Thanks or the feedback, and I appreciate you taking the ime to post the links
