This is a large homebrew that has the primary goal of allowing you to play as actual true dragons in a DnD setting without being unfairly overpowered.
To accomplish this...
A) I've included some guidance on how to better balance high level content
B) I've designed eight dragon-only classes, which are equivalent in power to the existing bard and wizard classes.
C) I've re-introduced a simple mechanic that allows martial characters to function much more effectively in combat; Flat Damage Reduction.
D) I've playtested it and refined it constantly for months
Also it contains a few new feats and spells that are suitable for use by humanoid characters! Complete with my personal guarantee that all of this stuff is at least as well-balanced as basic 5th edition DnD.
And... DONE

Thanks a lot for undertaking the effort of translating the entire class into homebrewery! It's a lot of work, but it really helps making the class more readable. I also love how you used notes/descriptive text to distinguish between the "actual" text from your opinions/guidance.
I think it needs a bit more clean-up, but it's a solid base to start from. A few nitpicks:
The following are suggestions and personal opinions: they should be treated as such and can be discarded if you don't agree with them, no offence taken.
For example, THIS is what I came up with, although you could certainly improve on the design or alter it to your liking. I added the archetype and the colour to the heading, alongside the character's name, because it allows the reader to immediately discern the most important aspect of the character. I'm not sure if you're done with the chapter or if you plan on working on it still, but in case, I'd suggest adding additional info such as AC, HP and Speed to make it possible for the player to pick the character and immediately run with it.
