What is the biggest difference between modern Western painting and traditional Western painting? How is this change perceived?

The change in technique! Traditional painting is represented by the Renaissance, which was a period of religious dominance, where the connection between the figure and the god had to be drawn! Leonardo da Vinci was one of the best at using this technique; but his skill with light and shadow also gave him extraordinary results. Modern painting emphasizes the subjective consciousness of the individual, so that various schools of painting sprouted up on the basis of breaking the divinity! Change: It was a change that had to be made under the onslaught of the zeitgeist, and the painters catered to the needs of the present world to some extent! No longer were they painting for the upper nobility! Orhan ~ Pamuk of Turkey: the historical novel "My Name is Red" explains this very well.
