I see the point of the image, but sorry it isn't really striking enough to distinguish the before and after.... She does have lovely eyes, reminds me of my partner, very similar colour and texture, :-)
Very creative!. I think you could have gone with an even tighter crop- the empty space of the forehead is not really needed and doesn't add anything to the shot. A tighter crop might help bring the eyes out more. I also think the left eye came out quite clean, but the focus on the right eye looks softer (even on the reflection). I'd love for this to be almost completely symmetrical/identical on both sides except for the makeup- that would make the difference stand out more.
I get the idea of half-done eye makeup, but it's not that interesting a subject matter to me. Perhaps if you had half of a clown's face painted up (or something where the before/after is more dramatic) it would have been better?
