4 i guess you´re a victim of the limitations of your camera. i´m saying so, because i feel you wanted a macro shot of the eye, but ended up with this perfect-rule-of-the-thirds-shot, but nothing more. i think even digital zooming of the eye and some colour manipulations would result in a more interesting photo. good luck, although this photo gets the lowest score i vote on this challlenge.
Lighting is the biggest problem with this shot, try to use an off camera lightsource next time when you try this, direct flash is never really flattering. A good suggestion would be to use the light from a big window during an overcast day or some kind of artificial lighting that is like I said, off camera.
