It’s a very good app, don’t listen to others
I saw some bad reviews on this app, so I decided to take a look at the app to see how it’s like (tl;dr at the very bottom) First off: the tutorials, while they aren’t completely step-by-step, they give very good advice on how to enhance and detail your drawings. They also give general details to look out for, which are fundamental to help give basic structure to your drawings I took a quick look at the videos and books, and to be honest they’re merely entertainment and advertising, respectively Additionally, the “draw” section is quite unnecessary since you can literally practice with pencil and paper... (TL;DR) Overall though, I think the app is good for helping give detail and further structure to your drawings; it’s not really supposed to give you a complete course, rather it’s just there to help a bit. I actually bought the book “How to Draw Manga: Basics and Beyond!” recently and from what I can tell, the book is TONS more helpful and I’m looking forward to using it!
