This chapter felt a bit weird, with the time-skip with the contest already having ending, and we didn't even see Machida's and Tsukishima's pieces who won T-T. Nice to see them having great progress as artists though, and I like seeing how Tsukishima has grown confident (like a proud samoyed indeed).
The critique thing, it seems obvious to me that it's just Machida trying to kick everybody new out, even those with some developed talent and genuine curiosity. He's a harsh and direct fella, but it feels like there's no good will in how he critiqued the guy from page 15 for example, even if though he actually gave there some genuinely good advice (I wonder if it's the same guy who called Sakura sensei a liar on page 18). Also, the grading thing, even Machida said in his own thoughts that it was arbitrary, so come on man, those are just intimdation tactics and him flexing his knowledge and seniority. The scene isn't over yet though, and maybe not everyone new besides Machida's friend left, so let's see when the new chapter comes out.
As always, thank you very much for the scanlation.
