Graphics Help! (I need Help lol)

Hey guys does anyone know why my Background is looking like this when I upload it to Youtube?

There is the link to my Channel and you can see how the BG is uncentered but the BG normally looks like this and it isn't showing the full BG.

So do you notice how most of the left side isn't showing and that it isn't centered on Youtube? Any ideas? Would appreciate the help. Thanks! Also even when I adjust the crop on Youtube it doesn't fix anything.

I'm pretty sure you can crop your picture to put the image where you want exactly

follow these steps I guess?




Hope it helped.
But in my opinion, your background is perfectly fine where it is.
