That at skin recipe sounds like Razza's. And seeing as he worked with 'Eavy Metal, it is no surprise that you got it out of WD. I really,really like it though and I'll have to try it sometime, though I struggle putting so many layers down on faces.
OK Bloodfather that sounds to me like one of a possible few things, so here goes;
1. Your paint isn't thin enough and you're losing detail shape as the heavier layers dry. (BTDT)
2. Wrong size brush so that you're overloading the underlying shape.
3. You are unconsciously struggling to see the detail you are working on and may need to consider some kind of non-prescription magnification. (
But don't just rush out on this one.This is your eye health I'm talking about here so be careful. My own eyesight is "damaged" and I have to use reading glasses to see anything inside three feet and clip on magnifiers for mini's. I don't want you to risk straining your own eyesight just because I suggested it.)
4. Perhaps your approach to the painting is not conducive to what you are aiming for. (If you go into the Articles and look at the Faces with Expressions one I did, take a look at the Chaos warrior face I've used as an example. He is painted in the same manner I still use today.{OK not the same paints}
Eyes first. Get them 'structured' with VMC Ivory and a pupil in place.
Basecoat. For me that's VMC Brown Sand. Carefully go round the eye socket, missing the Ivory obviously, then do the rest of the face and into the hairlines, if any. This should take two to three thin coats.
Now this is where it gets complex, so think of this; the head shape is round but the sculpted structure isn't. Think of the face as sets of TRIANGLES which have to be highlighted (not just the nose).
For a start look at the eyebrow ridges the base starts at the eyebrows an the apex is at or towards the hairline.
The forehead has a triangle in between the two eyebrow one with it's base at the hairline an apex above the nasal bridge.
In between these two triangles is the darker skin tones.
Now applying the same principle you can define areas on the face to consider as triangles, eyelids, cheeks, nose, upper lips, chin.
So with this concept it's the balance between the triangles and the darker areas you need to work on.
For me I tend to use a mix of VMV Violet Red and Brown Sand as the darker skin tone these days making a very dilute tone and carefully shading the eye sockets and sides of the nose. DO NOT WASH OVER THE ENTIRE FACE.
(DR's Rule of Thumb No 1: if you can see the first tone of shadow you've applied at arms length..it's TOO DARK!)
Then using the same paint shape in the darker skin tones in between the identified triangles where you want to highlight. Alternate between placing a highlight shape and a darker tone.
(DR's Rule of Thumb No 2: You ain't gonna get it perfect first time, Practise is your mistress, and Patience is your Lover.)
So here's the advice I was given by Mike and Ali McVey:-
For our purposes the face needs to not be thought of as a face but Areas of Emphasis.
Think of a capital letter
T pace it so the cross bar is on the eyebrows and the staff is down the nose and that is where the smoothest and highest emphasis of highlights should be.
Think of a capital letter
V place the point on the chin and the arms running along the jawline that's your mid strength structure.
So why think like this? Because when we look at a portrait of someone our tendency it to look to the eyes first so those areas we've defined as T and V shape the rest of our visual impact response. Giving the model face "areas of emphasis" like this makes us respond subconsciously as we would to a real face.
So take a look at some photo's of famous people (Sir Sean Connery is a great subject for this) and try to identify the shapes and areas on the pictures as I've discussed. Perhaps that way you'll get into a painting way you'll become 'happier' with.
Here endeth today's lesson!
