there are blown-out highlights, some have blurry areas, some are underexposed or have too little contrast
B&W pics don't do so well - best to leave in colour. For the others, 9jpeg - out of focus and the highlights are blown out; 2jpeg, the sun is blown out - no detail and composition isn't very good; 4jpeg, white balance is wrong, the composition isn't good and the foreground is too dark; 10jpeg, focus also isn't good; 7jpeg, lacking contrast and vibrance, composition - what are you trying to show? There isn't anything here.
Have a read of this from Adobe about how to create better photos:
It might help. 😀
Adobe Stock customers expect highest visual and technical quality for print & digital ad campagins. See links below.
Put yourself in the customer's shoes. Ask yourself 1) "Would I buy this image?" And 2) "What would I you use it for?"
If the answer to either question is "I don't know" then it's probably not suitable for Adobe Stock.
Better luck with your next submission.
