Composition is 90% pseudo-science and you can't refute that. Some people love dynamic symmetry and musical harmonic resonances. Some people think composition is just leading the eye. Some people base their compositions on geometric shapes. Some people just ignore composition entirely and do what looks cool. Everybody has different ideas on what it is, yet all of you act like its a settled science.
pic related is a painting by Vilppu's composition teacher, Lorsor Feitelson. Does this look like it has a good composition to you? Is it a beautiful painting that you would buy for $75,000? Yet this is based on all his composition theories that he passed down to Carmean and Vilppu, which are theories that he gleaned from Renaissance painters. This is what he spent his whole life working on and working towards. Was it worth it? Or was he deluding himself?
