Modeling from reference plates

I just finished the next step of modeling, using photos of my face as reference plates in 3Ds Max. I drew quads using the line tool, over the topography that I already mapped out on Photoshop. I converted those to Poly, then attatched them all into the same object, selected every vertex, then used weld, so that it formed one large flat surface, with the edges following the right features of my face. As i've done this before, I imagine the next step is to start dragging these vertex back using the left view, so that they are spread out on all 3 axis. Then create a mirror, or reference version, and stitch them together to make the entire face! After that, I'm not really sure where or how to start attatching this onto a head or body.

Well, I'm done for the night, see you all tomorrow.
