Fill Stitches

 on my blackwork project.

The fill is set for the overdress and is in black and gold.  I have completed the black part and am pausing to contemplate more fully if I want to deviate from the pattern at this point.

I am wondering if a small fill in maybe dark grey on the underskirt would look good and also if  some fill on the wall in a lighter grey between the swirl sections would work.

Or possibly something on the embroidery cloth.  Either, or for those options or even all three. (that might be a bit much but contemplating is fun)
