It's a little clunky looking but I am excited to do more in this way. It feels out of my comfort being less perfect and less detail than I'd usually put in, but I like the style and its fun to paint.
I painted the board beforehand called a 'colour ground' with a dull, Burnt Sienna/Ultramarine mix.
I used the complemantary colour Red-Violet (pink) and Yellow-Green. The Yellow green is the background but doesn't show up in pic.
