Hi @Jesus24616513j4ls , when your photo is viewed at 100-200% magnification, you can see a lot of artifacts in the sky.  This is probably due to the nature of camera phones and the automatic processing the phone does to compensate for the small sensor size.  I also agree with Jill regarding the white balance and the image is too blue.

Here is a screenshot of your image at 200%, although the artifacts were visible at 100%.

Creating good stock photography with your camera phone is not impossible, but you will face a few challenges.  Here is a link that offers some good advice on how to get the most out of your smartphone's camera.

Best of luck in your future submissions.
