What you need
This is the easiest perspective. Draw an horizontal line.
Draw 3 equals parts in the line. This marks are the width of the nose that have the size of an eye (approximately)
Draw to vertical lines and a small base in the middle space
Draw a line on each side. Join the top of the vertical lines with the sides of the nose. And join with other line, the sides of the nose with the base in the middle space.
Draw a semicircle on the middle space, and another in each size, now we have the basic form of the nose. We have to add details (you can see how it looks when is finished, on the left size)
First, draw the nostril. Is truly important, it helps making the shape of the nose
Delate the line that connect the nostril. Draw the shape of the fin of the nose
Now it's when the shadows give you the realistic part. Draw the shadow that comes from the nostril
To give the appearance of an upturned nose, draw subtle shadows that begin in the nostril. Give it a rounded appearance, but don't forget that have to the subtly.
Put some shadows on the fin of the nose and around them too. It's important to see where the light comes from in the draw to make this shadows.
Front nose is done!
To draw a nose side we have to draw a triangle with an angle of 90 degrees.
Add a little base in one size, and connect the lines from the base to the triangle.
Divide the base of the triangle in half to form the profile of the nose.
Draw 3 equal parts on the tip of the nose.
With circular strokes draw the basic shape of the nose
In this part you are going to give the shape to nose. Don't be afraid of not respecting the basic shape.
Draw the nostril and erase the lines that connect it with the tip of the nose. From the tip follow the line down as you can see in the draw .
Add some shadows down the nostril and over the tip of the nose so it looks more like a snub nose. And you finish!
This is the hardest one. Start with an horizontal line.
Draw to lines forming a triangle, one is longer that the other.
Now we are going to mark 4 important points. You can see them in the picture. The ones that is draw on the horizontal lines marks the width of the fin of the nose.
Counting from left to right, we draw 2 parallel lines between the point number one and two a a you can see in the picture.Now we draw another one since the fourth point,join the line making a triangle
Basic shape: draw a semicircle since the first point to the third, the second point is the middle. And the fourth point is the fin of the nose. From the second point add a little line
Erase the lines that connect the tip of the nose with de nostril
Give shape to the tip of the nose, Add a circular line on the side of the tip to represent the fin of the nose that we can't see. Draw the nostril, it's important and marks the shape of the nose
Add all the shadows, down the nostril and beyond the fin of the nose. Put some shadows behind the bridge of the nose and in the fin of the nose that we can't see. Congratulations, you finish!
Feel free to ask any question or how to draw other things ^^
