It's difficult for beginners in illustrator, but it's good for those who have been using it for about 3 months. I think the lecture content itself is okay for those who are interested in isometics. I'm personally satisfied.

It was a bit difficult to learn, but you explained it so well that I was able to follow along quickly. I was going to have to make a map for my company soon anyway, so that's a relief ㅠㅡ I hope you make a 3D design next timeㅎㅎ
