Looks like a good start, you'll have clothes covered later in that tutorial and for the hair as it's a low poly cartoon style model you should be able to get individual hair strands simply by modeling them using the same techniques with lofting surfaces and converting to polys as i think is used for the belt in the tutorial. For the viewports all controls are on the panel menu bar above, not sure i got it right but if you go to panels > layouts/saved layouts you can set the viewport layout as you like. Then go to panels > perspective (set individual viewport to perspective) / orthographic (front, side, top) / panel (render view and other things) should just set the one and not all. Hope that helps, Nilla
