MY 1ST PHOTO WAS REJECTED

Hi, I'm a beginner but I'm really passionate about photography.

My 1st photo was rejected because probably it hasn`t a good resolution?? because I didn´t put any filter on it.

It is the message 

"Thanks for giving us the chance to consider your image. Unfortunately, during our review we found that it features excessive post-processing and/or noise, so we can't accept it into our collection.

Excessive artifacts/noise can be caused by low light, bad camera settings, strong compression or excessive post-production.

If it was due to post production effects, know that our customers typically prefer to add their own special effects, filters or black-and-white conversions to fit the needs of their projects, so adding these effects in advance drastically reduces the market for your image."

any feedback for me.

Thank You 

Caro
