Change Stroke color to a lighter shade of the eye color and stroke width between 5 and 7. Using the Pen tool in Freehand Mode, draw a curved line below the pupil for a colored highlight (see image #1 above). Click Apply.
Switch to Ellipse tool and a very dark shade of eye color for fill (no stroke). Draw an oval that will become the shadow cast by the eyelid. We'll need to do some node editing to get the correct shape. This shape will cover nearly all of the top half of the eye. The shape we want here is sort of a half circle with a concave bottom (see image #2 above).
The first step in editing nodes is to right click the shape and select 'Convert to Path'. The Ellipse has 4 nodes: north, south, east and west. Use the Pen tool to select the south node and drag it upwards until it covers approximately half of the pupil. Next, select the east and west nodes with the Pen tool (hold Shift key down to select more than one node), right click and change Node Type to Cusp. Adjust the handles on these 2 nodes to create a sharp turn. Position all nodes until top half of eye is covered by 'shadow' shaped similar to the one in above image. Click Apply.
Next comes the white highlights. For Chibi these are quite large! Place a large white oval in NW portion of eye. This will cover some of 'shadow' color. Place 2 small circles in SE area (see image #3 above).
