The value of an artwork comes from the knowledge of spirituality and life that the artist has. Some works surprise, sober up or inspire.
Others, through their simplicity, their purity, show us equanimity.
Then there are those full of warmth and finesse, which inspire fullness.

Finally, other works are of lesser value, but still manage to transmit emotions.
Even without technical mastery, they express a life, diffuse feelings.
I think this last category is also worthy of interest.
