It looks really nice, and it's not a popular design so you can make it unique to your brand, but if you want to use it for the video backgrounds look somewhere else.
The brook theme has the a limited ability to create video headers. Limited because:
1.It slows down your side dramatically
2.You can only use YouTube videos
3.The YouTube video information doesn't hide
Additionally some of the design choices are weird and are hard-coded so you need some code knowledge. For example, the mobile menu button is on the right-hand side but the drawer slides out from the left.
You need to make changes to your server, and some server changes are more complicated than others. For example, I found changing the PHP string limit impossible.
I gave it a two-star because the page layouts look nice and they quickly respond to support tickets. But the lack of fully functional background videos, the incorrect position of the mobile menu button, and a somewhat difficult installation, make it hard to recommend this theme to others.
I will edit my review if any of the issues are fixed.
