This is right, particularly with regards to the face.
Lots of versions have had really good body-designs and logos, from Young Justice to other Boursassa designs.
Depending on how his powers work, the YJ facial design might be fine too.
His powers should work like the Rebirth version, where almost every cell of his body is cybernetic. That level of self-mastery actually explains the logo-- It's just a form of self-expression, since that's what other heroes in the DCU do and since he wants to be recognized.
If his powers work like that, you can just use the Young Justice design. Age him up if you feel like you have to.
If there's a tragic period for him it should be when he's still mastering his powers, like most other heroes.
The internal conflict can pop up in ways besides looks. He can still question how much agency he has (like the DCEU), still deal with his father's expectations, still deal with the loss of his mother, still deal with government security fears, deal with atheism (since he died and was reborn), etc. In terms of father-son dynamics and being a hometown hero, you can always look at
Creed as a blueprint.
Then you move on to making him smart and entertaining to read, develop his mythos, etc. You can have this character humorously fighting Kaiju in Japan one minute and then seriously engage in conversations on technological development and what that means for the world (like Black Mirror). You can cover telemedicine, police surveillance, etc. That's what 90% of the book (or whatever medium the story is set in) should be--fun and thought provoking.
