Eye practice image - iqew

First and second try for painting the human eye. In the first sketch I noticed that the eyebrow is probably too high up and maybe too small (even for a shocked face, which I didn't plan to do actually). Also, the iris is way too small. So, I tried to do better in the second one, but the eye is a little askew, didn't watch out for that at the beginning. Also, I'm still not sure about the eyebrow, I'll work on some more with reference next time.
