I watched the anime several years back, and have wanted to read the manga for some time. Some scenes from the manga are also clearly found in the anime, I recognized a few scenes. Other than that, it was at times confusing, it took me a while to get used to the characters again.
I loved the jokes and how they all had fun drawing and creating art. I will be sure to check if I can find book 1, 2 and 3 and maybe even 5 and further (if they are out already).
I would really recommend GA to all who like 4koma stories, jokes and stories about art. 🙂
