When it's really dry, I like to smear on acrylic paints with a paper towel. I like soft blended edges. If you want bolder lines, use an old credit card. Torn paper edges lend themselves well to smeared paint.
When the paint was dry, I added on elements and blended them into the background with more layers of paint.
More detail, and I worked on her hair. Wasn't all that thrilled, but I kept on going.
I ended up adding more details with some inspirational words and two women who are friends at the bottom, symbolizing our friendship that has lasted for many years. I fiddled a lot with her hair and face, and painted some fish, plus added some fish pictures I found, which were tiny! Then I let it all dry before I varnished it. The acrylic varnish really deepens the colors and the details.
I took the last picture outside, and also captured a picture of my "rioting" mum on the front step.
