Icon and design for the YouTube channel

Good day! I have an empty channel. It is necessary to create an icon and design for it (background). Theme of the channel: at the initial stage (for which the picture is required) there will be a video on professional editing of videos. Channel style: I’m shooting against a green background, and there’s also footage of my room (I can add a screenshot if necessary). The video adds footage from Adobe Premiere Pro (screen shooting). A view of the studio can be found on the Internet. I can send a photo of the computer, which I mount (his frames are also available).
