There's a Marvel superhero I've heard of that you might like, in that case. His name is Colossus, and from what I have heard, he's this intimidating Russian guy who has this very wholesome and clean-cut personality. Sounds pretty similar to the kind of person you're talking about here.
I love this comic. Great sense of humor and I like the way you used speech bubbles and stylization to really bring out the vibe.
