I think I can share something you are going to like, indeed. Whenever I need a good looking mockup for a magazine, or brochure, or even for a t-shirt I use LS graphics website, that’s where the best quality is at the moment. And you can find the Magazine Mockup https://www.ls.graphics/mockups/magazine-mockup there as well. I will recommend it to you and to everyone else, so go for it and have a nice day.
