Glossy Smiley

1. Create a new transparent canvas, 100 x 100 pixels. Set your colours to default (D).

2. Use the Elliptical Marquee Tool to draw a circle as big as you would like (40 x 40 pixels should be good enough). Remember to hold shift while dragging so that the circle can be perfect.

3. Use the following blending options:

Outer Glow

Bevel and Emboss

Gradient Overlay

Stroke

4. This is what your face should look like right now:

5. Now let's add the features. Make a new layer. Begin with the eyes; Line Tool and set the weight to 2 pixels. While holding shift, make a short diagonal line. Now create a diagonal line that goes the opposite way. This will form a triangle with no bottom line. Use the image below to help you. Rasterize this layer and make another copy of it so that you can use it for the second eye.

6. Make a new layer. Make an ellipse using the Elliptical Marquee Tool (It should be the size of the mouth that you would like it to be). Now hold Alt and draw another ellipse partially over the first one. This will cut off the extra part of the circle that you don't need so that the mouth will look like a banana. Fill in the mouth. Use this image to help you.

Use the same blending options as you used in step 3 with the following minor adjustments:

A. Uncheck bevel and emboss
B. Uncheck gradient overlay
C. Select colour overlay and use colour #FFFFFF.
D. Make the stroke size 2

Here is the final result:
