My first python plugin review

[origamifreak2]

Hello Everyone,

I have just finished creating my first gimp plugin and I wanted to see if there was anything I should do differently, like best practices to follow, etc. The plugin works as is, but is there any way to improve it?

Here's a link to the plugin code https://github.com/origamifreak2/Gimp-Pl...by_nine.py

The plugin converts an image to a 16:9 aspect ratio and ads a blurred background as padding.
