Using this thoroughly explained, detailed flash lesson, I will explain to you how to draw realistic human tears. To create this lesson, you have to use some special flash tips and tricks and Color Mixer Panel. Let's start!
Step 1Create a new flash document, press Ctrl+J (Document Properties) and set Width to 200 and Height to 150px.
Step 2Double click on Layer1 to rename its name into a background.
Step 3Insert a new layer and name it tears.
Step 4Take the Oval Tool (O), Stroke Color must be switched off, under Fill Color choose any Color, hold down Shift key and draw a "Circle". Look at the picture below.

Step 5
While your "Circle" is still selected, open the Color Mixer Panel (Shift+F9), and set the options from the picture below.

Step 6
Take the Gradient Transform Tool (F), and set your gradient in the "Circle" like it is shown on the picture below.

We're done!
Have a nice day!
