not meaning to belittle your comment quik as i agree with it, but a lot of zbrush users will model the eyes as part of the head as it makes it easier for them to lay the eyelids over them. a few crits that i've said before, it looks to me like this model looked like this 2 or 3 subdivs lower, the problem is that you generate really quite good bases, and then subdivide them a whole bunch of times, you really need to use every subdiv and revise your anatomy, take a look over the pixologic forums, you'll find tonnes of great anatomy studies, also something that people tend to do is they take a plane and subdivide it so that they have a workable surface from there they sculpt just an eye or just the nose, give this a try it'll help
