Position a background image inside a container

Hi, i'm struggling to get a background image (it's inside a GB container) positioned.

here is what i have - https://movinggiants.org/

The tiger is perfectly visible on Mobile view but on desktop it's head is cut off. I need to position the image lower on desktop but how?

In the desktop editor view it's positioned like i want btw. Only the frontend of the site shows the image positioned higher

Thanks,
Mario
