Element 3d Shaders - rejected

I’ve just received my first rejection for my first uploaded item. It was physical shaders pack for Element 3D v.2.2
All of them were photographed or hand painted by me. I got few questions and I hope that anyone can help me.

  1. I didn’t used the Envato logo and “only in Videohive” tagline in the video preview. Is it bad or good?
  2. I put a pdf help file, not video tutorial.
  3. I didn’t put a project file, only shaders pack with pdf Help file.
  4. All shaders textures were in .png and .emf format, in total 78 types in 1.88 GB’s zipped file.

Where is my mistake? Any suggestions are welcome :slight_smile:
