That's pretty much what I was going to say... it needs a little spit and polish. Not to look amazing or fill it up, but it's looking like a rough draft that needs a bit of editing and retouching.
The concept is great though, but again, it can be expanded on... take it and really run with it, because I think it has the appeal to definitely get you some good sales.
Oh, and thanks for the invite to see it.
