Is this only the sculpt, or is this the retopo? If it’s the latter, do you have the mesh?
At a first look, the biggest thing I’m seeing is in the ear… almost looks like you have a double Y (the Y formation and then a Y off of that). Also, with the neck, the two muscles up at the front feel a bit too defined for hte pose to me (though I think this is something that can vary somewhat. It feels more defined like it would be under tension with the head raised or turned to me. Also, I think looking at some references really quick it feels like it’s too wide at the base. Most of the women necks I’m seeing are more of a V shaped in that area (even if the muscle feels less defined in the references I was glancing at, you could detect more of a V shape to the neck muscles.
Overall, though, it looks great to me so far!
