I haven't seen the series, but after reading your post, I noticed that on many occasions the set and character design seems to be done using a watercolor and crumpled paper technique, with which a unique look is achieved. I guess that's why you say it's not for 3D and CGI lovers.
No he visto la serie, pero luego de leer tu publicación, he notado que en muchas ocasiones el diseño de escenarios y de personajes parece estar hecho utilizando una técnica de acuarelas y papel arrugado, con la cual se logra un aspecto único. Supongo que es por ese motivo que dices que no es para los amantes del 3D y el CGI.
Just like that my friend, it is a very specific animation that I personally find very top notch but I understand that there may be people who don't like it. That's just it, it looks like everything is handmade. I think it is unique and worth watching.
