Dear Dregnaught, This pretty good for only your second try with AR. Most of this looks pretty good. The eyes are probably the most important to get right if you want a good likeness. Of course nose, mouth and shape of all count too, but eyes seem to be the first thing people see. The hair that you have isn't bad at all, it could probably use a couple of small hi-lites to define the shape and style of the hair. Color doesn't really matter, you pick what you like and use it. All colors in a painting are influenced by the light that they are in, so if you imagine a violet light soirce, your hi-lites will be violet. Good luck and keep practicing.
