nice one burt, i have a couple of tips i think you might like
1 make some lines hidden (entity info box) like where you use two components back to back, like at the feet / knees. hide the joins so it looks like they are one
2 intersect the sphere (select - right click - intersect with model) at the 'pelvis' with the leg bits - this will show the joints here rather than the white blob look you currently have
hope these help - keep it coming!
