Describe in a few sentences, why you think artists rarely use symbolical balance in their work? what are some ways artists can create visually appealing composition?

Because it is, or can be when over-used, trite. Don't people tend to be more interesting the more unbalanced they are? Also, if there is too much symmetry, the eye (or ear, or mind) is not drawn anyplace in particular; everywhere you turn, you are at a place that you could think of as an artistic 'center of gravity'. I think the sense of balance and composition in any art should draw you in, and not just let you slip freely.
