You have so many distinctive figures and characters, there is no way you can cut it without loosing something. If it were me, I would choose an icon from the material, use the lavender shade so prominent and applique it over some of those spaces to enhance the ones around it. You didn't say how wide it is, but if is 45 inches, yes, I would cut it to be 54 inches long or if 36 cut it 45 inches long. Then make a beautiful brown border.
Please don't cut it into pieces. You will loose the intention of the designer. If applique is not your bag, Just quilt and quilt and quilt around design, until it is finished.
I bet you would get many raves over it.
