Yes we been recommended on our open day/assessment day to step a bit forward on the pic, but do not cross our legs.
If you have to send them a CV just copy a passport size pic on it with a big smile
I would recommend the red lipstick for the picture.
Otherwise if they do a primary CV selection probably the picture and the experience is the most important, maybe you could also write a little motivation letter on the bottom of your CV.
Good luck!!
