I think I'm still in time for Laura Harms' Weekly Challenge #5 the paper in my new Papaya Art Journal can take a good deal of saturation. This was done with Micron and Pitt brush pens. It looks a little better than it appears in the scan.
I knew I wouldn't be in time for Weekly Challenge #4, Starry Surprise, but I did a couple while I was traveling anyway. I was a bit more successful there than with Orbs, but I think I learned more with Orbs.
