Me too I think the more neutral image used today is the best, not hinting too directly to what many consider to be kinky. But this should be the decision of the female members of this site, so I suggest you contact them in a message exclusively adressed to them.
I also suggest You make a section exclusively for the Female members here where they can discuss between themselves as Dommes without us sub males peeking in. That may also attract more females to this site.
I also think most of the sub males here also are on other contact sites, and may have contact with domme Women there. They should suggest Domme Women in their network to look into AboutFLR.
