How to make this Illustrator file fit as a YouTube channel art
I need help perfectly cropping this picture so it fits onto the YouTube channel art area:

At the moment, it doesn't look the way I want it to.

I have tried cropping it to 2560 x 1440px that Google recommends but it still looks terrible.
How do I make it so that I can see the whole picture when I am looking at it on a desktop?
