Have you considered doing a female-female version as well? I could see you starting with the same first image as if you were seeing it from the other side of the bridge, then continuing the girls' story as if it was just slightly out of sync with the boys, like they showed up at the bridge on different days.
I was stunned when I first saw this piece by how awesome and how great it looks. I actually didn't find this by looking on deviantART, but in fact my boyfriend sent it in a text and how the characters crazily look like us. I am tall and light skinned and he is short and darker than me. There was another beautiful part about this picture that was crazy to us. That part was that the fact that he wants a boy and I want to have a little girl and there they are. me with the little girl and him with his boy. all in all I am here to say that this picture is amazing and I cant wait to see what kind of art you will post next. This pic is my wallpaper for my laptop now
would be cool to add a children's book narative to it.
