Hello silverspawn, nice progress so far. I agree that a little more tweaking will improve your characters anatomy. As far as hair goes, I've used Shave and a Haircut. But if you don't have that, you can create curves that resemble some of the hairs. Then attach the hair paint fx brush of your liking to the curves.

Simply select a curve, then select the hair paint brush in your visor, then go to Paint Effects>Curve Utilities>Attach Brush to Curves. You'll then need to tweak the brush attributes to get it all to look right but that might at least help you in the right direction. However, if you're not used to using paint fx brushes, it might be a little overwhelming when you try and tweak it. There are TONS of attributes.
