It may seem I'm getting lazy, but that's only half the truth. I'm a busy man, heh. I'm back now though, with some profiles I drew from reference. Ref: http://ncarpello.deviantart.com/art/profile-71396349 For this one, I accidentally drew the eye too far in the front, but I can't bother with that now. The picture is too small and the brush is too big. I'm not too good at finding references, so since google failed me, I just browsed deviantart a little. Ref: http://signalbox.deviantart.com/art/Bianca-Blue-Profile-89559976 I like this more than the first sketch.
Some more practicing, with profiles. I tried some facial expressions on the bottom two faces, which is probably the biggest reason why the bottom right face looks so strange. There's some strange geometry going on in the picture if you watch the characteristics of the faces too.
