Thank you for your submission. We have completed our review of “Christmas 2020” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.
Here is my project: Dropbox - christmas slideshow.mp4 - Simplify your life
thanks for your feedback
Hello. I think your slideshow is too repetitive, photos come and go always the same way, and motion definitely needs easy/ease keyframes to make animation more fluid. There are no transitions from one photo to the next, or some camera move. Depth of field is not well executed. Background is very basic and the particles effect needs more work and complexity.
If you are going to make slideshows, check other approved works to see the difference about the quality needed to upload a project here, is the best you can do before start a new project.
Hope this helps.
Good luck! 
Thank you very much for the advice! I am a beginner and I just have to learn.
