I like the shape of it, but to me it looks very unfinished. Try adding some knobs, buttons, an LCD display, or even some incandescence to the blood. The texture seam is pretty obvious inside the watch, so if you plan to shoot a scene that shows the inside of the watch you might want to think about fixing it.

The concept of paying by blood is weird.
