I like the characters, they definitely look interesting. You have a good sense with reflective light, but I think the background is a bit lacking for appeal. As for the foreground, I also believe that the values could have been a lot more contrasted; there isn't much in terms of shadows. Take the girl's furthermost arm. It has the same value as the shadows as under her neck. It should be darker. Nonetheless, the scene is very dramatic and that's always a plus! Keep on trying and you'll only get better.
