Thanks for posting, @TheJoshuaStreet. When it comes to background images on desktop vs mobile, a lot of the end result comes down to what image you chose. The radically different screen ratios of a phone in portrait mode vs desktop computer mean that a background image is going to have to fit into an area that is shaped totally different. You can see what I mean if you rotate your phone to landscape and reload. Your background image will likely look a lot better because it's now fitting into an area that has similar dimensions even though it's smaller.
I would try experimenting with different background images (we have a lot of stock images that you can use so you can do this right within the editor). The image you have there now could be added as a regular image element, too, which should then shrink more appropriately on a mobile device.
