"Balance" implies two sides. For every shoe there's a sock, for every salt shaker, there's a pepper shaker. For your pictued subject, balance it with a darker background subject that is not partly behind the subject. Or you could make it out-of-focus or even horizontally. Horizontal objects are viewed as submissive, angular or verticle objects are viewed as action-endowed or oriented.
Avoid having an area that draws to much attention or focus. Create a pictorial environment that invites a viewers eyes to take a tour of the entire scene. Have points of interest to follow from the foreground to background. I sometimes do that by how the whites or bright colors are distributed throughout a painting.
