Step 1:
Let's start out by creating a new file. I used a 600x500 pixels canvas set at 72dpi, and I filled my background with white color shade. Now make a new layer, using the Brush Tool with a large soft brush paint a black spot on your canvas. Then in a new layer draw an ellipse with #6AB9E7 color shade and 200 x 156 px dimensions on the black spot.
Step 2:
Under Layer Style(Layer > Layer Style) add an Inner Shadow and Inner Glow blending options to the light blue ellipse layer.
Step 3:
In a new layer draw a small and long white ellipse. Rotate the white ellipse through Edit > Transform and position it as shown below. Then set the layer's blending mode to 30%.
Step 4:
In a new layer draw a white ellipse with 89 x 89 px dimensions.
Step 5:
Under Layer Style(Layer > Layer Style) add a DropShadow and Inner Glow blending options to your white ellipse layer.
Step 6:
Create a new layer then draw a light brown circle with #F1D8BA color shade and 74 x 74 px dimensions.
Step 7:
Under Layer Style(Layer > Layer Style) add an Inner Glow and Gradient Overlay blending options to the light blue circle layer.
Step 8:
In a new layer draw a large light brown ellipse with #F1D8BA color shade and 142 x 152 px dimensions.
Step 9:
Under Layer Style(Layer > Layer Style) add an Inner Shadow, Inner Glow and Gradient Overlay blending options to the large light brown ellipse layer.
Step 10:
In a new layer draw a white slanted ellipse on the head design similar from step three.
Step 11:
Now in a new layer draw a black ellipse with 123 x 76 px dimensions on the head design as shown below. Then set the layer's blending mode to Soft Light.
Result:
