Since I rushed the drawing just to have something to do, I created something that just wasn't working in format. So I tossed that out and started over with a more horizontal format. Put the lines on first, then put the ravens down, placing them how I thought they might look best (I drew them on tracing paper individually, and then traced them where I wanted them on the watercolor paper).
Then I put miskit (Pebeo's Drawing Gum) over the lines that will remain white and while that dried a bit, I went back to the River Rocks painting and twiddled with that a while. (This painting on Cresent Board, bows when wet and you have to let it sit and dry completely before it shapes up again so it's a time consuming process but I'll just fiddle with it in between other things so I don't overdo it.)
