When starting on the first washes I work all over the painting, paying attention to maintain highlight areas, making sure that I am working away from areas that may still be wet. I also use this as a time to check for accuracy in the drawing by comparing the petal that I will be working on with the original photo. If something needs correcting I make the correction BEFORE I put any paint in that area.
You will notice that a few areas have more detail than just a first wash. These areas were begging me to pay a little more attention to them and being the sensitive, caring person that I am, I did.
