"really modern and polished" strikes my tastes as corporate in the world of zines. Just my opinion tho, not trying to gatekeep.

zines are interestingly their own subculture that sparked out of sci-fi fandom and punk culture, so anything more "polished" than those origins is going to seem corporate by comparison. This is a pretty good article that gives something to compare to (https://www.mentalfloss.com/article/88911/brief-history-zine...).
