Hi guys - nice variety of figures here.
If I may suggest, for those that cannot resist from using a wash to bring out details, hold the figure upside down and let it dry in that position as well. Reason being is to allow the dark wash to accumulate in the top areas of wrinkles and folds. Even so you will end up with the centers being darker as washes tend to recede from edges.
Here is something I quickly put together as how to best arrive at discerning light and shadows for a figure.
1. - spray the whole fig in a dark shade, you can go jet black but I prefer the base colour mixed as a darker shade.
2. - spray the base colour at a 90 degree angle as well as from up top. This will leave the the darker shade still visible in shadow areas.
3.- spray a mixed light shade of the base coat from a direction directly from up top - this represents the highlight area.
Now you can go in with a brush and create more contrast to your liking.
