It was really difficult with the light source cause if you look at the chin shadow on the neck, it looks like the light source was coming from the right side.......but I can see what you are saying also on the face looking like its coming from the left!! As far as a popping out png, I wasnt going for that at all its actually not transparent on the left side, its actually black, so I was going for just a sig look.....if you were to post it on a color background it would show up black on the left, lol!!
