I said it before, and I'll say it again. You should DEFINITELY be a game designer, you would make a FORTUNE off of works like this. Considering how FAST you threw it together, I'm amazed it turned out this good. My hat's off too you.
Believe me brother, if you did, the game you made would sell like Hot Cakes! Granted the story line and game play would have to be good, but on artistry alone, I think I would pay an arm and a leg for graphics like this.
