I think it'd be a fun character. They unfortunately decided that you couldn't fly while riding the dragon until level 15. I'd ask your DM if you could have it work like the Purple Dragon knight UA where you can fly up to your movement as long as you end your turn on the ground until you get the full flight feature. That way you can actually feel like a dragon rider and not just a monitor lizard rider earlier than lvl 15.
