You did an excellent job with your first BQ2 quilt. I too would outline the faces and stitch in the ditch. Depending on your FMQ would depend what to stitch on the Hot Pink fabric. I actually followed the zig and zag echoing the lines of the sewn pieces with straight stitching and I think I was able to mark it using 1" between the stitching line. I was very happy with the final results.
