It's a little hard to reply without knowing a bit about what you are trying to do.
Is V1 the "before" and V2 the "after?" Are you trying for a surreal look or a realistic look?
To get a bit overly-critical: Both photos are very contrasty, but that might be what you were trying to achieve. I am not a fan of the "blown-out highlight" look that seems to be getting popular right now. Nor do I prefer the green shadows look. In V2, the saturation is a bit high, and the lighting seems to be coming from two different directions. The compositing looks a bit pasted together.
Like I said, a bit overly-critical.... but you asked.
