Two newbies making our own classes

Hi 

Me and my friend who i play DND with regulary decided that we should try and make our own DND classes. It started as something fun to do and then try and play a oneshoot with our homebrew classes. But now that we are done with them it does feel a bit strange ;) Are they acctaly any good, would they work and are they balanced or not. Are they to powerfull, or not powerfull enough. 

I have a link to my homebrew class here. Any feedback would be much appriciated =) https://homebrewery.naturalcrit.com/share/cTvTaVbRWjkK

I didn't understand the raven rider. All classes must gain proficiency with simple weapons. Also does Shared Essence grants you unarmored defence;

How do you created them; I mean with which program;
