Don't they know there will only ever be one Marilyn.
But you have to give this lovely imposter an A for effort...
except for the finger nails -- no nail polish... ouch!
Light, expression on the face, posture, colour are simply wonderful ! No wonder,- it's Michael's work ! Yet , there are serious flaws composition and attributes wise. As you mentioned correctly, nail polish takes a bit of chunk out of Marilyn's charm, but this is not the end of the days...
But, there is no excuse for lack of grate with air blowing through and up in to Marilyn's skirt ! It makes me very sad that fine American traditions are not maintained....
