your comment surprises me (although I'm probably misunderstanding it ...) as the first thing I thought when I saw the mini, was 'oh, straight out of a frazetta painting', what with the helmet an' all ...
The outline matches the conventional Conan, but he's more characterful in terms of the face and build.
I quite like Frazetta's original work, but most of the subtleties of Frazetta's Conan paintings (especially in the expression of some of them) are lost when translated to miniatures. In the paintings you can see that Conan's not just a dumb thug, but you have to look mostly at the eyes to see it and most sculptors can't capture that.
Not that the old GW Barbarian Dr. Viking is using managed that, but instead the sculptor used a different pose and attitude to express what 28mm eyes couldn't.
For a different look, see this much more recent Conan:

It's otherwise sculpted to a high standard, but he looks like a hunchbacked neanderthal. The sculptor missed the forest for the trees.
