You can tell when I’m unable to write when a ton of drawings start cropping up instead. I recently got both Adobe Photoshop CS5 and Corel Painter 12 and have been experimenting with both. I find it easier to sketch/ink in Photoshop, but easier to colour in Painter. I was trying out the “Real Watercolour” brushes in Painter and it’s, uh, hard. (Just like actual watercolour!)
