Changes I would make to the play.

I honestly wouldn't make any changes to the play, because I don't see any faults in it. The only change I would make is to add to the play would some more explanations. Like how Banquo's descendants became the Kings of Scotland. Since Malcolm became King of Scotland in the end of play, instead of Fleance. I was really confused and the only explanation I could of think of was that Fleance's children married the Banquo's children. To be honest, I really think the play was well written and very enjoyable.

Banquo and his line descendents (Kings of Scotland).
