Experience level and professional field of the artist: The experience level and professional field of the artist will affect the speed of completing the case content map. If the painter has relevant experience and the professional field is consistent with the case content, he may be able to understand and present the case content faster.
Complexity of case content: The complexity of case content will also affect the time required for drawing. More complex content may require more time and energy to understand and present.
Details of the image: If the image to be presented is very detailed and accurate, it may take more time and effort. On the contrary, if the image is not so detailed, the painter may finish the work faster.
Therefore, it is impossible to give a clear time range. If the case is complex and requires detailed images, it may take weeks or even months to complete. If the case is simple and the painter is experienced, then a few hours or days will be enough. For more specific time information, please consult relevant painters or institutions.
