Concept painting
Painting with the concept is the biggest difference in my all painting.
So, you can find the brush stroke on the first few strokes, it represents what a concept is going to form in a design.
It could be a dark shadow area connected together, based on similar value but different hue, that will create the biggest color area, that create the biggest impact on audience vision.
Under the concept we have a bunch of tools to build it up, for example, we can use color value edges, these three visible tools on the palette can be organized in multiple ways to form this concept.
What is the concept anyway? it is a kind of feeling about what you see in nature and try to bury some more interesting factor inside
