I have been using mudbox for a few months, but last night I got my hands on Sculptris (while looking for a trial of Zbrush). It seems like a good free alternative to Zbrush while I am saving up the funds to purchase that program. Anywho I have sculpted a number of characters before, but this is my first attempt at a realistic female human bust.
I need LOTS of feedback, so please comment. I'll post updates as I progress through this process.

I'd say you're off to a decent start, but the best thing to do right now is focus on your references and anatomy. Pay attention to the big shapes, blur your eyes and compare your sculpt to any photo of a real woman.
Get that ear in there and then move around all your big shapes until the proportions look better, then you can start refining features. No matter how detailed features are, they'll never look correct if they are the wrong size or in the wrong place.
