How to design Your writing system (and which one to choose)

Woah, it's been a few months since my last video. I started making this about two weeks ago, a lot more effort put in than my last video.
I hope you like it (i rushed towards the end of production so i'm sorry my voice sounds a little choppy) have a nice day!

Made using Paint.Net and Windows Moviemaker, more info on how i did it here:
