Teeny tiny doodle of Wisteria's dad (Patreon)

We'll be seeing him in the present for the first time in the comic, and I'm struggling to make him look older. How do you make a 30-ish year old look 40-ish??? Adults don't change all that much in a decade, and I don't want him to look dramatically older because then it might look like he's aged because of stress or something, which he hasn't. Art is hard!

My solution is to grow out his hair. It might not make him look older per say, but at least it indicates that time has passed?
