I work through paintings instinctively. My colour wheel is memorized and I just pull what works. Most days... I am so "into" the painting process that I don't even always remember how I achieved certain effects, or mixed a colour....
but not today.
Today... as I struggled to get that smooth, youthful, glowing, skin...and then I remembered..... the hard pastels!
I understand that pastel should be applied the same. Thin to thick, which would mean a hard pastel first... and top layers should be softer and thicker. I do this... in areas where I want to see texture. Where I want the stroke of the pastel rough, and painterly like the angel's skirt, and wings.
