Please help me why my project was rejected

Overall, the design of the graphics and execution of the animation feels outdated, and doesn’t comply with today’s modern techniques.

I’m sorry. I don’t know how to insert a video.

Why was my project rejected? from huangting on Vimeo.

Idea is not bad. But project needs much more visual variations (camera moves, different angles, transitions, more details on screen) and maybe you could make it more dynamic too (looks a little slow).
Good luck!!
