An important feature of byzantine art was its

Byzantine art is almost entirely concerned with religious expression and, more specifically, with the impersonal translation of carefully controlled church theology into artistic terms. Its forms of architecture and painting grew out of these concerns and remained uniform and anonymous, perfected within a rigid tradition rather than varied according to personal whim; the result was a sophistication of style and a spirituality of expression rarely paralleled in Western art.

it would usually depend on the genre that they would provide

it's all focused on the way you angle and put all of these this in pespective. say you wanted you artwork to be famous, you would want to align and put all of these into grasp. the imagery give off a good descriptive matter. proportion is aligned with the color and mood. balance is how you place everything and if there is too much or too little of. design is the main thing if you want your art to be amazing
