Perhaps you have seen them on ArtStation or ZBC but its a collective portfolio for the YCFCG course from China. The results are fantastic and I had a chance to speak to a Chinese/English speaking student who sang their praises but did state that if you only spoke English, it would be really difficult to attend.
Well now they are offering an English class, http://www.ycfcg.com/cg-character for $1000. Has anyone attended, had any exposure to the class or know someone who has? Very curious but for $1000 I need a bit more assurance.
