Update on Winds of Color

For the last few days, I've been stitching on Winds of Color. I finished the lady's skin and the dark blue clouds surrounding the pink on the left side. These were all in basketweave. Today I completed the moon (which I originally thought was the sun, but the text says otherwise!) and the lavender areas around it. These areas were stitched in skip tent to let the shading of the background show through.

Unfortunately, the line through the middle of the section also shows through! On the picture of the finished piece, there is some stitching over that line, but I can't find anything in the directions that tells me what that stitch is. I think I'll try a stem or outline stitch.
