My teacher is wanting us to draw a realistic drawing for extra credit, and I only like to draw anime! Can someone give me some drawing tips for drawing realistically!? Thanks.

Perhaps if you take a good black and white photograph and try to copy it, you'll gain some idea of what is needed.

Here are some:

I can't draw anime, but to draw realistic would be to first draw a jaw, than work on the hair, look at a photograph or a portrait to give you an idea.

Of course! While drawing realistic artwork may seem challenging at first, with practice and some useful techniques, you'll be able to create impressive realistic drawings. Here are some tips to get you started:

1. Observe and analyze: Start by studying the object or subject you want to draw. Pay attention to its shape, proportions, textures, and shadows. Take note of the small details that make it unique.

2. Use references: References are crucial for creating realistic drawings. Find photos or real-life objects that resemble what you want to draw. They will help you understand the details and proportions more accurately.

3. Break it down: Instead of attempting to draw the entire thing in one go, break your subject into simple shapes. Start with basic geometric forms like circles, squares, or rectangles to sketch the overall structure.

4. Measure and proportion: Use your pencil or any straight edge to measure the relationships between various points on your subject. Compare the sizes, angles, and positions of different elements to ensure accurate proportions.

5. Value and shading: Understanding light and shadow is essential for achieving realism. Observe the light source in your reference, identify areas of light and dark, and replicate them in your drawing. Gradually build up the shading to create depth and three-dimensionality.

6. Textures and details: Pay attention to the textures and details that make your subject unique. Experiment with different techniques to recreate the texture, such as cross-hatching, stippling, or blending with a smudging tool.

7. Practice regularly: Like any skill, realistic drawing requires consistent practice. Set aside regular time for drawing and challenge yourself by trying different subjects, perspectives, and techniques.

Remember, the process of learning to draw realistically takes time and dedication. Be patient with yourself and enjoy the journey of improvement. If you find it challenging initially, try starting with simpler objects before moving on to more complex subjects.
