Thanks guys,
@andy_vs around 105k tris, Maybe I could go a bit higher ? I notice in some of ur tut videos you were talking about bumping up the geo in specific areas to allow for more detail (using mixer), but I haven't played around with that much.
@kishchris settings for the epidermis were combination of a few different material layers to tweak bend,shear,tensile and rest scale values, mostly for the inner thigh, a weak constraint over the whole thing back to the slab, as well as pinning down the knees and head with something a bit stronger.
