It is actually a very low poly count from the looks of it.  The hands may be the exception.  I haven't actually opened the blend file, as I don't have need for a base model like this one, but it looks fairly low-end.  Nice work on the form of the upper legs and chest.  The hip needs some adjustment but not a lot.  I cannot comment on the back side, though.  Butts are kind of difficult to get right at this level of detail.
