Practice worksheet for drawing and shading basic geometric shapes.

The image you've uploaded is a drawing and shading exercise designed to teach the principles of 3D form and shading in art. It presents five basic geometric shapes: Sphere, Cube, Pyramid, Cone, and Cylinder.

🔍 Task Breakdown:

The worksheet has three columns:

1. "Draw your forms" – This column shows line drawings (wireframes) of each shape.
2. "Shade your forms" – This column shows fully shaded versions of the same shapes with proper light and shadow to create depth.
3. "Now it’s your turn" – This is an empty column where you are supposed to draw and shade each shape yourself, following the examples.

---

✔ Goal:

You are asked to:
- Draw each 3D shape in the third column.
- Shade them properly using techniques like value gradation, highlighting, and shadowing to make them look realistic, just like the shaded examples.

🎨 How to Approach Each Shape

Let’s go through each shape and explain how to draw and shade it based on the examples:

---

#### 1. Sphere
- Draw: A perfect circle.
- Shade:
- Light source assumed from the upper left.
- Leave a bright highlight on the top-left side.
- Gradually darken toward the bottom-right (shadow side).
- Use smooth graduated tones (from light to dark) to show curvature.
- Add a soft shadow beneath the sphere to ground it.

> 💡 Tip: The darkest part is usually opposite the light source.

---

#### 2. Cube
- Draw: A cube in perspective (typically 3-point or isometric).
- Shade:
- Identify which face is closest to the light (top-left).
- That face is lightest.
- The face farthest from the light (back/right) is darkest.
- The side facing away from the light gets medium tone.
- Use hard edges for shadows between faces.
- Add a cast shadow underneath.

> 💡 Tip: Keep edges sharp; avoid blending across corners unless showing reflection.

---

#### 3. Pyramid (Tetrahedron)
- Draw: A triangular pyramid with one face visible at the front.
- Shade:
- Light comes from the top-left.
- The top face is brightest.
- The side facing right is darker.
- The bottom-left face may be in shadow.
- Use smooth gradients within each face.
- Darken the base edge where it meets the surface.

> 💡 Tip: Focus on planar shading — each flat face should have consistent value.

---

#### 4. Cone
- Draw: A circular base with a pointed apex.
- Shade:
- Highlight near the top-left curve.
- The side facing the light is lighter.
- The opposite side curves into darkness.
- The base should have a soft gradient.
- Add a core shadow along the bottom edge.
- Include a cast shadow under the cone.

> 💡 Tip: The shading wraps around the curved surface smoothly.

---

#### 5. Cylinder
- Draw: Two ellipses connected by straight lines (in perspective).
- Shade:
- Light hits the top-left curve → bright highlight.
- Gradient down the side to a dark band (core shadow).
- The bottom-right side is in shadow.
- The bottom ellipse (base) should be shaded slightly darker than the top.
- Add a soft cast shadow below.

> 💡 Tip: Use circular gradients to follow the cylinder's curvature.

✔ Final Step: "Now it's Your Turn"

In the rightmost column, you need to:
1. Sketch each shape using clean lines.
2. Apply shading using pencils (or digital tools), mimicking the examples.
3. Pay attention to:
- Light direction (consistent across all shapes).
- Value contrast (light vs. dark).
- Smooth transitions (especially on curved surfaces).

📝 Summary of Shading Principles Used:

| Principle | Description |
|--------|-------------|
| Light Source | Assumed to be upper-left in all examples. |
| Highlight | Bright area where light hits directly. |
| Midtone | Area receiving indirect light. |
| Core Shadow | Darkest part of the object’s own shadow. |
| Cast Shadow | Shadow projected onto the surface below. |
| Gradation | Smooth transition from light to dark. |

✔ Example Output (What You Should Draw)

For each shape in the "Now it's your turn" column:
- Draw the outline clearly.
- Shade with three values: light, mid, dark.
- Show form through value changes, not just lines.

---

Since I can't draw directly here, I recommend:
- Using a pencil (HB to 6B range).
- Start with light sketching, then build up layers.
- Practice cross-hatching or blending for smooth gradients.
