Good attempt at an eye. To make it pop out more have the iris under the lid darker, just a darker blue, and outline the iris in a darker blue. Do a subtle reflective shine one one side of the iris (where the shadow would be) and lighten where the light side would be. Just then a matter of putting a few proper shadows that also would bring out the squiggles of the iris (that's the official name you know:}) Make the lashes nearer the inner eye smaller, nearly non-existent (upper and lower lashes) and as they get to the outer edge they get bigger. A slash of white going over the eye ball pupil and iris to make it slick and round.
