I can see right away how carefully and successfully this was done. Considering all the different styles women do up their eyes, you very rarely see artistic license on the eyes themselves! There's so much symmetry between the eyes, it's hard to believe this was all freehand! They look deeply creepy, and worried.
It could use some digital cleaning, sharpness and whitening (and adding to the chopped bits at the sides). Eyes seem a tad too close to each other... but that's completely understandable considering... see, you coulda fixed that digitally, if you thought it needed it.
