YouTube Redesign

I visit YouTube every day. I love watching videos there, but I think it has several UX and design problems. So I decided to see how it can be improved and designed my own version of video watching page. You can read details about it on my website:

And to show how my design works I coded a prototype of this page, which can be found here:

Almost everything (that doesn't lead to other page) works there, so feel free to click those buttons.

Feedback will be appreciated.

Cheers,
