1. Realistic approach: Capture every detail of the subject’s face by observing and replicating their features as accurately as possible. Utilize proper shading and blending techniques, making the portrait look like a real-life photograph.

2. Impressionist style: Use short, quick brushstrokes and vibrant colors to depict the essence of your subject rather than striving for perfection and precision.

3. Charcoal or graphite sketch: Create a monochromatic portrait using pencils or charcoal to depict fine lines, shadows, and textures in a dramatic way.

4. Drybrush technique: Apply paint sparingly to a dry brush, painting in layers to build depth and texture in the portrait.

5. Pointillism: Using small dots of color, recreate your subject’s image by placing complementary colors in close proximity for an optical blending effect.

6. Abstract expressionism: Experiment with non-representational imagery by focusing on color harmonies, bold shapes, and gestural brushstrokes to evoke emotions associated with the subject.

7. Cubism: Deconstruct the subject’s appearance into geometric shapes and planes for a modern, fragmented appearance.

8. Pop Art: Use bold color contrasts, simplified forms, and iconic imagery inspired by popular culture to create a statement piece.

9. Palette knife technique: Forgo brushes altogether and use a palette knife to apply thick layers of paint that create bold lines and textures within the portrait.

10. Watercolor: Utilize the flowing nature of watercolor paint for delicate washes of color that result in luminous and transparent facial features.

11. Fresco: Discover the ancient art of fresco painting by applying pigments mixed with water onto fresh plaster for an authentic historical portrait.

12. Silhouette painting: Focus solely on the profile of your subject by creating striking contrast between light and shadows using only black paint on a white canvas.

13. Glazing: Add thin layers of transparent paint over a monochrome underpainting to create rich and luminous colors that mimic the glow of natural skin.

14. Edo-style (Ukiyo-e): Inspired by traditional Japanese art, convey a unique sense of elegance and simplicity using delicate, precise lines and soft, muted colors.

15. Collage: Combine multiple techniques or materials such as photographs, fabric, or found objects to create a unique and personal portrait with added depth and meaning.
