Advice On My Landing Page

Hey guys, im not 100% sure if this is actually allowed, but I personally dont at all see this as self-promotion.

Ive been starting html coding slightly lately, and I have created a landing page for my friend and I's gaming community. I would like to get some advice from you guys on what is good and what isnt and what could be changed or even added.
I would like some constuctive critism please :)

I know that when the video is clicked on it currently takes you to our trailer on YouTube, I need to change the video on the landing page to the trailer. I was using the TTT video for testing.
