Good study... I dont know where Pollorojo gets off on his critique, This was 4 years ago so I'm sure you already know but remember the TOP lid is the one that moves.. generally not the bottom what so ever.. watch your iris sizes and make sure your eyeball fits snuggly into the eye socket. Bottom two aren't bad but they have some rather striking issues. The eyebrow needs to follow the brow line and the lids wrap over the eye ball... also the eye shape isn't always almond especially when in 3/4 views and the like. Top one is rather close. All in all good work, and considering this review is 4 years late and from what I've seen of your newer work, I think my critique on this piece is rather lost...

so like its just practice then?

its okay, the eyes have a nice gleam to them, and a little bit good form. That's it
