Chiaroscuro, which started in the Renaissance, can be tricky for artists. Here are some of the main challenges:

1. Complexity: Knowing how to use light and shadow well takes a good understanding of shapes and how things look from different angles.

2. Different Techniques: The materials you use, like oil paint or charcoal, can change how effective chiaroscuro is in your artwork.

3. Ideas and Concepts: Making depth look realistic can be hard and sometimes frustrating.

Here are some solutions to overcome these challenges:

• Look at classical artwork to learn different techniques.
• Practice often to get better at it.
• Try out different tools and materials to see which ones work best for your style.
