Material design admin template hard rejected

Hi,

Our new admin template was hard rejected, please help, how can we improve it?
Here is a demo: http://lambdathemes.in/monster/source/

Thanks in advance!

Start from zero.

What do you mean? Is it so bad?

I hate Material Design but Yours is just to simple … when I check some accepted admin templates, they have much more functionality.

Thanks for reply, please, can you tell which parts/pages we have to improve?
