How much is it appropriate for the painter to buy out the original portrait?

The price of the painter's original head portrait varies with the painter's popularity, quality, size, market demand and other factors. The buyout price ranges from several times to dozens of times the original price of the painter. Specific price suggestions refer to the following aspects:

1, painter's popularity: the works of famous painters are more expensive because their works are more popular and valuable.

2. Quality of works: The higher the quality of works, the higher the price.

3. Size: The larger the size of the work, the higher the price.

4. Market demand: Market demand is also an important factor affecting prices. If a work is very popular, its price will be correspondingly higher.
