This is some of the freelance work im doing at the moment for Kingdom Death.
I've got permission to show a WIP for this miniature - she is the Preacher.
I start by taking my pre-constructed base mesh and getting her into the pose and simply start blocking out all the other bits and pieces. Notice I'm going straight for the pose rather than sculpt her symmetrically.
I do this on my own choosing, It would be faster doing it symetrically but im learning much more about forms and weight by tackling the sculpts more like a traditional guy would.
