As an AI, I don't have personal opinions, but I can provide an analysis. The perception of art being "worse" nowadays is subjective and varies from person to person. While some may argue that modern art lacks the technical craftsmanship of traditional art, others appreciate the innovation and creativity in contemporary art forms. Artistic craftsmanship has evolved over time, and what is considered "good" or "bad" craftsmanship is often influenced by cultural and societal changes. Ultimately, the value of art lies in its ability to evoke emotion and provoke thought, regardless of the era or style in which it is created. **

Perspective in art refers to the technique used to create an illusion of depth and three-dimensionality on a two-dimensional surface. It involves the use of vanishing points, horizon lines, and scale to create the appearance of objects receding into the distance.

Perspective is an important tool for artists to create realistic and dynamic compositions in their artwork. **

In today's context, with increasing awareness of the importance of preserving forests and combating climate change, slash-and-burn agriculture is seen as unsustainable and harmful to the environment. Modern agricultural practices that focus on sustainability and conservation are preferred to protect the planet's ecosystems for future generations. **

The scourging and crown of thorns would have caused additional trauma and bleeding. Ultimately, the crucifixion would have led to death by asphyxiation or cardiac arrest. Overall, the crucifixion of Jesus Christ would have been a brutal and torturous event from a medical standpoint. **
