To me, good abstract art conveys “passionate intentionality”. You should be able to feel some of what the artist was feeling when he/she was in the process of painting. Abstract is to fine art like jazz is to music.
When I began painting abstracts, the idea that kept running through my head was “beautiful chaos”. That’s the way I see creation. I see the beauty of a very intentional creator but there is also an element that looks pretty random or chaotic on a surface level.
