maranello55, several people have asked me that recently, and I don’t have a really clear answer. Like most others, I want to work on something really cool, to me that means like feature film or short film, or an unusually cool TV series… not games so much, I’ve done that.
ArtisticVisions, The nose and the lips are good, just the skintone seems a bit too pale and yellowish. The eyes and eyebrows need a bit of touch-up, check out Linda’s eye painting tutorial in the Art Discussion forum, that should give some hints. The eyebrows: they seem light grey now (not sure if the character is supposed to have silver eyebrows?), maybe colorpick the color from the darkest shadow on the nose and use that to paint the brows… don’t paint every hair, squint at your reference and try to paint the blurry version you see. The eye on our left: it’s too almond shaped, needs to narrow on the outside. Both eyes have lower lashes that seem too thick and black. Also, the dark ring around the iris seems too black… but a good start, overall proportions seem ok. This 45 degree angle is very difficult.
overcontrast and RanZ Cross, thanks.
paperclip, the red of the shadows doesn’t seem to go with the greenish lighting… the black lines outside the nostrils should probably be softened. The chin seems an odd shape, no dip under the lower lip… the eye on our right seems bigger than the other. Ears seem a bit too flat against the head. Basic shape of the head is good.
roberte, “Would you please explain your thinking re. contour rendering as opposed to the ultra realism of your direction until now. I recently read some of the articles relative to the “Uncanny Valley” principle and in part agree with them.”
Yes the ‘Uncanny Valley’ effect is part of it.

“For me, the artists job is to interpret reality, not to become a camera”
Yes I agree completely.
“being able to create believable charactors for a script I have written, cast them in a movie based upon my vision and have it be perceived as real”
The first part, yes, but that last part about ‘real’ - it would be just as cool, or maybe even cooler, if the movie is just one notch more stylized than reality, I think. ‘Sky Captain’ was a good example of this (though the soft-lens effect may have been a litte strong for some).
I’m trying to find a good compromise. I believe I can find one, where the lines are actually making the imagery more beautiful, yet still keeping the overall feeling very close to reality.
warcross, thanks, glad to help! 
I think this will be my last reply here, so let me just say it’s been a pleasure, thank you everybody, and most of all Leonard for inviting me.
