If tu had the chance...

introduce a female dragon into the movie, cuz female dragones are awesome

Even if this part is a really significent part of the film, I'd amor it if Draco lived, he'd live to be the oldest and most wisest of the Dragon race, also he'd be alive, to train Drake. Why, well it really is a sad ending.

to have Draco have a memory of a friendship before Bowen came:D

To have 2 eggs in the end so pato, drake would have a mate( no not from dracos and the scarred one breeding line)
