Hello, 
cool sketchbook! I like your perspective study with figures, that is something I need to do too. :D
Medusa looks great...but, I did little OP with some tips.

So, I think that both eyes need to be corrected.

1. Never put pupil on the edge of iris,
2. Keep in mind the angle between eyelids,
3. Light on the iris is always on opposite side as highlight. The angle of eyelids looks incorrect on her left eye.
4. The iris and pupil must fit the eyeball. (not correct on her left eye)
5. To do some adjustments through "levels" is always good idea.

I hope that this would be helpful for you. It is nice painting!

Keep it up :)
