Twitch Mockup - Super Basic

My first time actually trying to design a mockup or anything in general, I am trying to learn some visual web design and I had no idea what I was doing but it turned out decent. Still learning, any constructive criticism would be nice so that I could improve! Still working on it, it's a test to see what I could do at the moment. Nothing fancy. NOTE: Some links are directed to opening on the actual Twitch Website! I do not own anything from Twitch and other companies.
