How to Draw Lips

Bước một bước

1. Bước 1

   Draw a light horizontal guide and a vertical centre line.

   Lips are close to symmetrical and the eye is unforgiving about it, so the centre line is not optional here. The horizontal marks where the two lips meet.

   Cẩn thận! Working without guides because the subject looks simple.

   Kiểm tra The two lines should cross at the middle of your page.

2. Bước 2

   Draw the line where the lips meet - a wave, not a line.

   This is the most important mark in the drawing. It dips slightly at the centre under the cupid's bow, rises on each side, then turns down into the corners. Draw it slowly and get it right; everything else is placed relative to it.

   Cẩn thận! Drawing it straight or as a single smooth curve.

   Kiểm tra It should change direction at least three times.

3. Bước 3

   Mark the corners of the mouth and how far apart they are.

   Mouth width is the proportion people get wrong most often on a face - it is wider than you think, roughly reaching the centre of each eye. Marking the corners now stops the lips creeping inward as you draw.

   Cẩn thận! Drawing the mouth too narrow.

   Kiểm tra Both corners should be the same distance from your centre line.

4. Bước 4

   Draw the cupid's bow: two shallow curves meeting at a dip.

   Not a sharp M. The two peaks are rounded and the dip between them is shallow, and on most faces the whole thing is subtler than the version in your head. Keep it inside the middle third of the mouth's width.

   Cẩn thận! Making it too pointed and too wide.

   Kiểm tra The peaks should sit within the middle third of the mouth.

5. Bước 5

   Run the upper lip edge from the bow out to each corner.

   It thins as it goes. The upper lip is thickest at the centre and almost vanishes at the corners, and drawing it at even thickness the whole way is what produces the drawn-on look.

   Cẩn thận! An upper lip of constant thickness.

   Kiểm tra The upper lip should be visibly thinner at the corners.

6. Bước 6

   Draw the lower lip as one full curve.

   The lower lip is fuller than the upper - commonly about half again as deep - and it is a single continuous curve rather than two halves. Sweep it in one motion from corner to corner.

   Cẩn thận! Making the two lips the same depth, which reads as a cartoon.

   Kiểm tra The lower lip should be clearly deeper than the upper.

7. Bước 7

   Darken the line between the lips until it is the darkest mark.

   Go over it and commit. That dividing line is in shadow at every point along its length, and it should be darker than anything else on the page. Timid here is the commonest reason drawn mouths look weak.

   Cẩn thận! Keeping it at the same weight as the outline.

   Kiểm tra Squint. The dividing line should be the first thing you still see.

8. Bước 8

   Deepen the corners into small dark pockets.

   The corners of a mouth are recessed, so they are darker and softer than the line between the lips. A small dark note at each corner, fading outward, is what makes the mouth sit inside the face rather than on top of it.

   Cẩn thận! Ending the mouth line in a hard point.

   Kiểm tra Each corner should fade out rather than stop sharply.

9. Bước 9

   Shade the whole upper lip a middle grey.

   It angles away from the light, so it is darker overall than the lower lip. Shade it evenly first and add the variation afterwards - trying to do both at once is how the upper lip ends up patchy.

   Cẩn thận! Leaving the upper lip as light as the lower.

   Kiểm tra Upper lip clearly darker than lower, everywhere.

10. Bước 10

    Shade under the lower lip, and leave a highlight on top of it.

    The lower lip catches light on its upper surface and drops into shadow underneath, where it also casts a shadow onto the chin. That light-on-top, dark-underneath pattern is what makes it read as a rounded form rather than a shape.

    Cẩn thận! Two symmetrical highlights, which look like plastic. One, slightly off-centre.

    Kiểm tra There should be exactly one highlight, off the centre line.

11. Bước 11

    Add vertical texture lines, in the shadowed parts only.

    Lips are lined vertically, and the lines follow the curve of each lip rather than running straight up and down. Put them where the lip is already darker and leave the lit areas alone - texture everywhere flattens the form you just built.

    Cẩn thận! Covering both lips evenly with lines.

    Kiểm tra The highlight area should have no texture lines in it.

12. Bước 12

    Soften the outer edges until they nearly disappear.

    This is the step that decides whether the mouth looks drawn on or grown there. Go round the outline and lighten it, especially at the corners and under the lower lip. Keep only the dividing line strong.

    Cẩn thận! Leaving a crisp outline all the way round.

    Kiểm tra From arm's length the outline should be hard to find.

13. Bước 13

    Go over the lines you want to keep, and lose the guides.

    This is the step that turns a construction drawing into a finished one, and it is the one most people skip. Press harder on the outline and the features; leave the small stuff light. That difference in weight is what makes a drawing look deliberate rather than traced, and it costs thirty seconds.

    Cẩn thận! Going over everything at the same weight, which flattens the drawing back out.

    Kiểm tra The outline should be clearly darker than the smallest details.
