Nah, wrinkles are normal for that era. If you look at people in their 30s from older generations on the internet, they often look older than people in their 30s today because of differences in beauty standards, skincare, healthcare, and lifestyle. And the lifestyle in the story is way harsher than what we experience in reality, so I think having some wrinkles is justified in the story.

I don't like how he's drawn; that beard is the only thing that makes him look like he's in his thirties, and he does not have features that scream he has lived a life. If he shaves it, he will look like a 20 year old guy who has never seen a fight. I wanted a rough looking guy. hes not dilffing enough for me.
