  About half way through:

      greet x = "Hello " ++ x
      main    = print (greet greet)

  (assuming you did mean the "main =" part). This looks like a type error to me (can't unify [Char] with (a -> b)).
  
  Nice, introduce GADT (without its scary name) right off the bat. Pretend like it's always been there. :-)
  
  You probably want more examples for the pattern matching stuff. You showed one example for each WTDI, but if you're really trying to teach it, you probably need more. Come to think of it, if you're really trying to teach it, you should get people to open up ghci at the beginning of your talk.
  
  Looks good so far. Get people hooked!

    1. Yes, it's an error and is updated to say such. Thanks. :)
    2. Indeed, but with 45min I can only try to make people not freak out.
    3. Thanks!
