A few suggestions...

I don't see any mention of "tolua".
I found this invaluable when integrating lua into my C++ game.
Makes it trivial to access C++ objects/methods.

Game developers will ask about performance, so you might
want to have some comparitive benchmark figures to hand.

Tell them it is free!!

A few more substantial code examples would help give people
a flavor of what the language is about (should be able to
get some from the lua website - the SPE paper has some
good ones:

A few more simple code examples would help clarify some points
e.g. "Variables are un-typed, only values have type" would
be given more meaning if you included a few examples, e.g.:
  function printVar(var)

  printVar({ 1, "string" })
  printVar(function() print("hello") end)

Concentrate more time on the "interesting/unusual" features
of lua (untyped variables, tables, tags, gsub) than on 
the syntax of the operations that you get in any language
(expressions/control structures) - people can easily pick
up the latter from the docs.

Mention that you can run it standalone (so people can
easily play with it to try it out).

Hope this helps...
