When something is rejected, Adobe give you a reason. It is not detailed, but it is very important. Please tell us their rejection message, otherwise people could waste lots of your time with the wrong theory.
Thanks for giving us the chance to consider your image. Unfortunately, during our review we found that it contains one or more technical issues, so we can't accept it into our collection.
