If it's your first game, I wouldn't plan on selling it. Most people aren't willing to pay for non-professional games. It's great that you're working on improving your maps. There are a lot of great mapping tutorials out there to help too.
Also, not to insult you, but I'd work on your spelling and grammar too. People will pay more attention to your game if your topic is more professional looking. This is even more important in-game. As I can see from your screenshot, you misspelled guard, unless his name is Gaurd, which it could be I guess, but it should be capitalized along with the other names.
