What's wrong with the quality of these photos?

Hi @WitchSpace,

You need to post the original size images just as you submitted it to Adobe so that we can see the possible reasons for refusal.

Best wishes

What do these images of cherry trees have that yours doesn't? 

Good composition, vivid colors, strong horizontal and vertical lines to draw the viewer into the scene... 

As a customer, which one would you purchase and why?

Hello,

You'll need to post bigger sizes - like the original size - to get meaningful feedback. Can't give it with thumbnail sizes.
