Next time you submit a demo...
You want to make sure it is a demo. This really is more of an artwork piece. That being said, I think you have a good beginning scene to a point and click game. I don't know if you have ever made a game, but prepare your self to invest a lot of time. Some times your best critics are your hardest. Take what the other posters have said and try to improve on it. I personally think it's a pretty good picture. Good luck and I hope to see a future game come out of this.
