Competitive Call of Duty Channel! HELP!

[Nutella]

Hey whats up guys, my name is Nutella and i would love some feedback on my channel. Lately i cant really think of what to upload, so i would like some ideas. I also want to know everyone's opinions on my videos, thumbnails, and channel art to see what i can improve on, thanks.

Thumbnails need branding.

Channel art is fine. Maybe add uploading schedule.

1 minute? imho, too short. Aim for the 3 minute mark minimum. Add an intro, add an outro card to watch previous videos and subscribe, etc.
