Examples: This image uses the elements of shape, space, colour, value & texture. The principles used here are: repetition, variety of proportion, contrast (light vs. dark) , movement and rhythm.
The trick is to be able to explain how they (the principles are used). Ie: Here we have a pattern inifying the background, bright variety of colour across the foreground, a large central face is emphasized and there is a sense of repeated pattern by the three front figures (essentially the same pose).
You try talking about the principles … How are the elements put together?
shape - form space – distance in and between line – thin, long mark made by something texture – look/feel value – degree of lightness, darkness, intensity colour proportion balance (symmetry) rhythm / pattern emphasis (focal point) variety contrast unity movement
