- Logo and banner look nice for themselves but they don't follow the same design. This would be essential for a strong branding.
- The banner could already contain information about your upload schedule.
- The scenes in the trailer are too long and a voiceover could make it more engaging.
- Place a call to subscribe at the end of the trailer.
- The "About" section is not bad but you could make it a bit more interesting.
- Place you social media links in the trailer description such that they show up on the channel page.
- Strengthen your thumbnail branding. They should re-use elements from your channel art such that somebody who sees one of your thumbnails recalls the channel.
- You voice recording quality is okay but there is room for improvement.
- Most of your titles start with the game name (boring). Start them with something catchy e.g. "Total demolition - Flatout 2

erby" instead of just "Flatout 2

erby".
- Use an interactive end card to lead viewers to other videos of yours.
- If you want to return the favor name one thing you would improve on my channel
