Great Idea and very nice layout!
Maybe could you try the person holding some sort of photo camera, if possible without having to show too much extra of the body. Maybe a camera hanging down from a strap and in white coming over the pants maybe ???
Also you can try and add a female leg or style of shoe or have a female version on her own instead. Would love to see this in a few other colour combinations or with a darker background.
Your on the right track, keep up the beautiful work!!!
