Eh, I wouldn't go straight for Delon, as he's way too beautiful, but I'd certainly move towards that direction. People forget that Tony's supposed to be a pretty mature guy. Yet they draw him as a random late-20s beardbro. Next thing you know he'll be dropping "mad scienzxce" bombs, talking about alcohol free craft beers and getting tattoos while collecting some stupid shit like Funkos. He's way out of character. This is gonna sound weird, but the most "Tony" appearance I got in recent times was his cameo in Wasp. The problem I think is that they give him really short or "messy" hairstyles, when he's always had his hair pretty styled.
Regardless, he does work better as a 60s looking guy. Really go for that Mad Men aesthetic, not Sillicon Valley. It makes Zeke utterly pointless.
