Not bad.
The style is pretty nice, and while the graphics and sounds are not amazing, you definetely show talent and room for growth.
You do use a little too much pulp-noir conventions, which is fine for an opener, but I hope you develop your own style or spin on the genre as you write more.
Because...
Many people who have seen the movie Sin city did not know there was some concept written other then a script of sin city, I don't understand why you can obviously use the style and concepts similar to sin city and then put some sort of rule on your reviews. You are a bullshitter, go watch some salad fingers, thats called originality. :-).
