Here are some pieces I did at my job for one client who wanted his face, his wife's, mother's, and father's face on Barbie and ken doll heads. The work flow went as follows: Faces were scanned, Barbie Dolls were scanned, Faces were cut off and put on to barbie doll heads. Hair was re-sculpted on all heads, Additional Sculpting was done on all heads. Especially the Grand Pa head, that hair was entirely re-sculpted from nothing. It was my job to do all sculpting and final touch ups to make the heads cohesive. It's also important to know that these are going to be printed out as actual Barbie doll Head size.
