Adobe Stock customers expect the highest visual and technical quality for use in professional projects like brochures, posters, merchandise, product packaging, movies, TV commercials, websites and more...
Before you submit Stock images, ask yourself "who will buy this image and what could it be used for?" If the answer to either question is "I don't know," it's probably not right for Stock.
@OCF5E13 Beyond any technical problems, since you are a beginner with stock photography, I'll mention this particular image has perspective and subject problems. For example, while the ground in front of the barriers is level, the buildings look as though they are leaning back or towards each other. The tree may naturally be growing crooked but because it isn't seen as straight in your snap, the perspective with the leaning buildings makes the entire scene seem dizzying (at least to me). There is also too much going on in the photo for the lens and distance and everything seems crowded. Think more about your main subject. Is it the tree, the metal sculpture, or the skyline? I hope this is helpful and keep trying!
