I’ve got from the head down to the waist started. Time to get a little more done.
For the pelvis, I again swapped out the cylinder for a sphere. Though I’m not sure that was the most efficient way to work with this section. A new cylinder probably would have sufficed. I had to do a little more work 
though. I flattened the top a little and even made it a little concave to fit the sphere for the waist. Next I flattened the bottom to make it easier to flare it out. With the sphere I was doing a little of working against myself. But I used the soft select tool. That allowed me to not over do the scale transform too much on the upper edges and still get the stronger scale transform on the lower ones. I still had to do a bit of adjusting to smooth it out better. Once the bottom was the right shape I used the soft select tool and used the point selection and concave the bottom of the pelvis piece as well. This provides a nice spot for the hip spheres to sit in.
I adjusted the size of the one hip sphere and put it in place and then I 
copied it over for the other side. I had planned on just making the one leg and then copying all the pieces over so this is a little ahead of what I intended. But I wanted it for spacing. I wanted to make sure I had the pelvis wide enough and that I didn’t get the next parts too wide to realistically fit.
The next component down the line is the thigh. I considered swapping the cylinder with a sphere for this one as well but I decided that was really unnecessary. I just swapped the existing cylinder with another one that had
cap segments so that I could better manipulate them. Then I selected the entire cylinder and scaled it in the x and y axis to so that the diameter matched with the hip sphere. Then I selected the bottom edge loop and using soft select I set the impact so that the taper would be most severe at the origin and then fall off nicely towards the top. Then I scaled it in the x and y again this time making a nice taper to where the knee would be.
Here we are so far.
It’s not that much farther along, is it. Hmm… I’ll see if I can get the base of this mannequin done soon so I can start trying to figure out how to rig it. That should be interesting.
