Sorry, I was a bit unclear: no, the last image seems to work just fine (eyes included!!!) :)

Well, I am grateful to you.
Had you not said that, I would not have desperately tried to make it better.
This is why I like you man. None of us cares for false modesty :)
Except that poor eyesight thing of yours :P I think you could take glasses if you wanted to :))
Sorry for the hijack.

Hehehe yeah I have a pair just like those.
Next phase is hair, I believe.
Lipgloss, eyeliner, brows are small challenges that can be saved for later.
Would you recommend Kristinka hair?
I don't even know the first thing about it.
But Softimage's hair module is really outdated and badlooking :(

The head was anatomically way off, so I thought of sculpting a bit. Yes, I did take it to ZBrush, but please don't hate me. I am only human :P

Okay, it's an improvement
(and ZBrush is merely an extension to SI, so I won't hold it against you)
The only criticism (yes, I'm back!!! :D ) would be that the cheeks in the second version could (should?) be slightly more pronounced...

That's a first, criticism from me with sort of an explanation :))

"The prosecution rests"...
Much better, I can't think of any nagging criticism at the moment... :D

When I tried the old textures on the new sculpted mesh, I realized they were way off.
So I have re-done the major areas once again.

I am feeling very tempted to do the final render in Zbrush, but I can't even seem to find the render options there, so I guess Softimage is the tool of choice still :P

Great progress. After your corrections in ZB i really start to like it. You were right with the proportions. Great changes! I would like to see her with eyes again to judge the face as a whole :)

Thank you Deracus!

I have re-done the maps since sculpting caused a lot of distortion.

This is the new bump:

Thanks for showing us your maps too... :-bd
Now I was wondering (also related to the "Skin Workshop"), what do you base your colors on? I imagine you haven't peeled the indivual layers off of your own skin or that of some distant relative...
Where for instance comes the greenish/blueish tint in the epidermal layer from?
I''m struggling ~x( to get to the "bottom" of this, please help me out... :ympray:
(You can also point me to some good reference material for all these layers, if you can/like)

I cannot use my skin because I am too hairy (not that I am bragging or anything :p).

The only good source, if you do not have expensive equipments and goodlooking bikini babes handy, is 3D.SK I am afraid.

I gather some references, then take front and side head wire screenshots and take them to photoshop. Then with the wire shots in multiply mode, I adjust the references underneath with liquify and warp. Then I camera project on the head from front and side, bake albedo. Then I combine them in Photoshop. Some distortions remain. Those I just fix in trial and error fashion. A few times I did painting in Blender, a few times in Modo... whatever is handy at the time.

The green patches thing is very simple. I just look at faces I like in the movies and stuff and see where redness is predominant and where it isn't. Then I make a copy of diffuse texture, take a hue/saturation adjustment and change hue to light green, and paint a mask on it. Then I take another hue/saturation and change to darker green and paint another mask. Then I take another, change to blue and paint another mask. Blue I have used very little though, under the eyes.

For the subdermal, I oversaturate the diffuse texture and use that as base. I took a large soft red brush and painted where skin and bone has more flesh between them, e.g. cheeks, ear lobules, the paddy parts around the eyes. Then I painted with dodge tool where skin is very close to the skull, e.g. the forehead. Then I put some red dots where the blemishes are.

A lot of guys go to extraordinary lengths and paint veins and whatnot. I am no good at that and I don't even try. Perhaps if I need to make the melting senator from X-Men someday, then I will have to :P

Ideally, epidermal should be like a dead dude's skin after a vampire attack :p and subdermal should be like you have skinned a dude (while no vampires are around :)) )

The thing is, I would feel good if someone who knows this craft would assure me that my workflow is good. Since that hasn't happened yet, I feel kinda uneasy. Perhaps this is all wrong.

Added a little makeup and eyelashes. I hope it's looking at least a little bit better.
Giving this girl loads of hair is probably not the best idea. It will deviate largely from photorealism in all likelihood.
So I am planning a hat or something. Any ideas greatly appreciated.
The small hat Shoshanna wore in Paris in Inglorious Bastards is a good one. I don't know what it is called. But I will find out.

First of all - Thanks for the explanation...
I assume the eyelashes are "texture only" too?
Two comments:
- One would expect some luxurious long hair on such a head, although the prospect to make it in Softimage can be daunting.
- Make her smile (a little), she doesn't look as if she's enjoying being part of the render at all... :D
