Alright, painting of face (& cleavage)
Following the same paint formula I used for the hands and legs, here is the face painted up, just with an airbrush.

Due to limitations of camera operator (me) it's not as sharp as I want. We can see how the flesh tones are lighter on the forehead and breasts (less muscle tissue - highlights too) and darker around the eyes, nose, neck and cleavage (either more muscle tissue, or a natural shadow spot)
Plus the cheeks have a degree of blush on them too. (that's where I added some sunset red to the skin tone)
Now, my shading efforts are trying to add life to this character. Here is what she looks like in grey primer, with the light falling on her.....

and here is a similar shot, now with the colour applied

So, by going for a lighter, warmer skin tone, I feel as though I am closer to where I want the figure to be.
( I could keep on fiddling around with it, however, sometimes things just have to be done!)
This is an experiment for me at this point, trying a few things new to me.
- using an airbrush for the majority of my shading and highlights
- moving from light to dark (rather then starting with a mid-tone, and adjusting from there)
- Sheer effect clothing (Stockings, in this case) and I am still working out how I will be approaching it, so there will be off bench testing in the future.
I am happy with my results so far, even if it means a rework on occasion.
I am still unsure if I will add more definition to the shades and highlights(flesh tones, that is); given that she will be wearing dark coloured jacket & skirt, thigh high black stockings, bra & panties (purple?) plus shirt, I feel as though if I go for a slightly darker skin tone, the contrast may be too low in the end. Just my thoughts, feel free to add your 2 units of currency worth
At the end of the day, I am the one who has to look at her, flaws and all.....so I am happy so far.
And as others have said, your second figure is better then the first, the 5th better then the 3rd, the 10th better then the 8th, and so.
As always, questions, comments, queries always welcome!
Hopefully, some better pictures can be taken soon!
Cheers
