There is no right or wrong in a work of art no moral imperative. The moralist can never be an artist. The artist must avoid quality. This is the ultimate acknowledgment of a higher power. God lives in our imperfections.
Good defect is good effect.
Where straight lines intersect is where your drawing occurs. Keep your palette clear. As an artist you are under no obligation to explain or justify what you are painting. You are here to paint, to express in paint who you are. Describe if you will but let s not insult the viewer with too much unnecessary detail or explanation.
