[WIP] female sculpt

Bombshell

I'll keep a long story short, I've been trying to get a good visual representation of one of my characters, I saw this as an oppertunity to get better at many manors of design, at the moment I'm trying to get better at sculpting via zbrush.
The target is a young teen girl roughly 14 - 18 years old. for the moment I'm concentrating on the face, I figure it better to take baby steps, I've sculpted before but I've never been very good.
Here is my current progress:

Crit as severely as possible, tough love is the best teaching practice.
any and all help appreciated,
Thanks for reading,

I'd recommend working at a lower subdivision and work out the big shapes and forms more. It seems like you didn't make much progress before adding a subdivision level [or increase the dynamesh resolution].

I'm swapping in and out of higher and lower resolutions, sometimes forms in lower resolutions end up with stretched faces which make the next subdivision divide messy, in which case I go into a higher resolution to get better results.
in this case I needed to do so for the nose, and its worked out okay I think.

anyone got any tips on eyes and ears?
