Understanding the difference between 2D and 3D shapes can be tricky when you're sketching. Here are some main points to consider:

1. Depth Perception:

• 2D shapes, like drawings on a piece of paper, are flat. You only need to think about how wide and tall they are.
• 3D shapes, like a cube or a ball, have depth. This adds another layer of difficulty because you need to make them look real.

2. Shading and Texture:

• To make 3D shapes appear lifelike, you need to know how to shade them properly. This can be tough for beginners who are just starting out.

To get better at sketching, it’s important to practice regularly. Spend time drawing what you see and learning how light works. This will help you improve your skills and understand shapes better.
