- Your channel logo looks nice but you definitely need a banner in the same design that also tells about your content and upload cycle.
- Use more like a best of in your channel trailer instead of a random video.
- Have a big subscribe button at the end of your trailer.
- You "About" section is generally fine but it would be better to use the first line for something punchy as it shows up in search results.
- You thumbnails should have the same design as your logo to strengthen the branding.
- Don't use the same thumbnail image over and over again. Show what is catchy about that particular episode.
- Start your titles with something more catchy e.g. "Three penalties in a row - England vs Spain FIFA Gameplay"
- Your audio quality is fine.
- Give a short introduction about what a viewer can expect on each video.
- Use an interactive end slate to drive viewers to other videos of yours.
- If you want to return the favor name one thing you would improve on my channel
