141104 Mask progress updates

I moved Sayaka's jawline up at the back (on Homura it looks too squarish; I'm considering trying to make a similar modification for her to what I did for Sayaka by carefully cutting out those segments and replacing them with new ones), made the tops of her eyes flatter, smoothed her cheeks, and adjusted her hair some more.

I adjusted Hibiki's inside, made the pattern on her headset more accurate, added cutouts on the earphones for the back "hooks", added the bases for the antennas, and made the headband wider. I decided to make the antennas and the back "hooks" out of craft foam rather than printing them, since they would probably be rather fragile if printed. I also started drawing her eyes/brows/lashes.
