What is the artistic value of Van Gogh's Sunflower? Who can introduce it?

Sunflowers use a large area of pure bright colors.

Picture jump,

Shining on people's hearts like sunshine.

Abandon pure realism

Traditional painting style without emotional thinking,

Dry brush strokes,

I feel that the sunflower has dried up.

This work

It is a typical representative work of Impressionism.

Van Gogh's Sunflower expresses an idea, a spirit and a life.

Where is the so-called value? It's just whether a painter can combine all his thoughts and painting contents perfectly.
