Please, no more flowers.  Stock already contains 28 million flowers.  😞

Dare to be different. Find other subjects to photograph in new & creative ways. 

Hello,

Taking photos for stock is not about taking photos. It's about commercial value; it's not about pictures of flowers, sunsets, and landscapes, but more about pictures that can be used in a commercial setting - generally speaking!!

Thinking commercially is really important!!!!

In addition, to what has been said: This is completely oversaturated.

In addition to the issues noted by @RALPH_L and @Kev Bell LRPS29410079  the overall composition is not pleasing. There are more than 205,000 photos of water lily images in the Adobe Stock database already, so the competition is stiff. Take a look at some of those images to get a better idea of the expected level of quality.

Lost traveler, it's unlikely that you will find the answer from Adobe "why exactly the quality of this picture isn't good enough" but I think Ralph Lear has provided some very likely reasons. I've had a look at your image file and I can see that you have not assigned a colour profile to it, you should assign the Adode sRGB profile to your image file. Here's some other pointers that may help including the requirement for sRGB: https://helpx.adobe.com/uk/stock/contributor/help/photography-illustrations.html#:~:text=Learn%20more%20about%20the%20Adobe,Color%20space%3A%20sRGB

Additionally to Ralph Lear's comments: there are several areas of glare (too bright) on the lily leaves which distract from the flower (this could also be regarded as a quality issue).

The file is not focused well, the white balance is too warm (blue), the blue outlines look unnatural and the blue square on the right side should be removed.
