I know we're not supposed to comment on loglines, but godd amn! It seems like every new set of scripts put up there is one that reads like it was copy and pasted out of babel fish.
First, no need for names in loglines. IMO that would include the name of the kingdom.
Obviously the grammar is very messed up, I would guess english is the issue, not your writing ability.
Also, this is movies, why say "some of the characters and events are based on real life?" None of us know the difference, so just say "Based on historical events." Nice.
A complete logline might read something like this:
"In 728 AD Princes and warriors clash over the love of a Mayan Princess. In the ensuing struggle kingdoms will fall and love will be betrayed... Based on historical events."
To me that's enough for a short.
I'd read the actual script, but it's in word, and my computer doesnt swing that way. Get Celtx, it's free and even I manage to use it.
Good luck with it.
PS If you want reads and advice from people, read and comment on other scripts...
