To draw manga on a PC successfully, you first have to get familiar with the tools of your chosen software. Also, study the style and anatomy of manga characters. It takes time and patience, but with consistent effort, you'll improve.
To download manga on PC legally, you could check out official manga websites that offer downloads. Another option is to use digital comic stores that have proper permissions. Just make sure to avoid any sites that seem sketchy or illegal.
It depends. Some manga reader apps are legal if they have the proper licenses and permissions to offer the content. But many are not, as they violate copyright laws.
MangaZone is a good one. It has a large collection of manga, and the search function works well. The app is easy to navigate, making it convenient to find and read your favorite manga.
