I wouldn't say it feels like DBZ at all. It's still a Shonen for sure. But it feels a bit like the very first version of Attack on Titan, from when the mangaka was making it as a contest entry for a magazine.
I'd even wager to say it feels a bit like Fist of The North Star for it's speed and sudden bursts of action.
I really dig your main character turning into a dinosaur\dragon. Right up my alley, I'll be subbing pretty soon. Keep it up, I like how over the top everything is.
