Good model, dramatic light. Nicely done!
The last one, as has been noted (more or less) suffers from raccoon eyes.
The FIRST one has a problem which maybe bothers nobody on earth but me: her pupils are not separated from her irises, at least not clearly. There's some catchlight going on there confusing the issue. Anyways, the upshot is that I think this makes eyes look weird and dead. Your mileage may vary!
