An exceptional shot. The snake seems sharper on your website, so there might be a little loss in sharpness in resizing the shot.
I think the whole tone and context of the shot is near perfect. I wouldn't try anything to make the snake stand out more. To me the leaves and twigs are as important as the snake itself.
I would keep everything as it is. The only thing I would try to avoid for future shots is the blurring in the immediate foreground, as it's a little distracting. Just needs a little more depth of field, to give you the room to crop out the foreground blurring.
