It is not at the quality level required to proceed, and you will not be able to resend this item again.
I want to help
I think there are several reasons for rejection. You have 2 seconds with nothing on screen before the reveal starts, it´s too much empty time for such a short logo. In my opinion, the completely white background doesn´t look good, maybe if you add some gradients, lights, shadows, small particles, or flares, that could help. Finally, the particles that reveal the logo look a bit weird and dont´t blend very well with logo.
Hope this helps.
