One of the main things I liked about this show is of course the details that go into each art. The lives of art students and students pursuing higher education in art was also portrayed elaborately. I didn't find this in other art stories - Kakukaku Shikajika (manga) was more about the twists and turns in an artist's life and Arte (anime from manga) focuses more on Arte's journey of becoming an artist. For me. Blue Period has a lot of fresh elements that I enjoyed.
Yatora's evolution as he learned avout various things felt so good! Each time he made a breakthrough, it felt like character development xD When Yatora talked to his mother about wanting to pursue art - how he only just realized how much effort she puts into caring for her family - the moment was do heartwarming ;A; I wonder how the talk with the father went. Both of them were so happy when he told them about the final results in the last episodes (mom's reaction was best tho). Speaking of reactions, Yatora's friends starting to cry was cute as well.
Speaking of Yatora's friends, at first, they felt like aloof people, as Yatora was thinking about how he had to blend in with them. But they really care about Yatora and they supported him so much. I remember that in one episode, Yatora was carrying his art stuff or something, so the glasses-dude was carrying Yatora's school bag for him. That simple thing made me feel, "ah, they're supporting him from their heart." And of course, they were shown verbalizing their support as well. That was super nice.
Oh and Yatora's conviction touching Koi-chan and driving him to pursue his own dream was also a nice touch.
Ryuujo/Yuka was a pretty influential character in this story. I really hope to see more of them in the next season (hopefully there will be one?). Exploring their character and life would be so intriguing!
The art teachers in this story were just fabulous. Saeki sensei and Oba sensei are the reasons why this story exists. Especially, I love Oba sensei. She's the human version of Koro sensei 😭
Okay, if I keep talking about each character I like, it's not going to end. Almost every character left an impression.
I just wanna add some brief notes about things I didn't like. The art felt like it could be better. In some places, it felt underwhelming and a bit...awkward (?) The biggest moment was Yatora first mind-traveling to the blue Shibuya of daybreak.
The music also felt a bit lacking to me. At some points, I felt that the music was just there, not influencing the mood in any way. It could be just me but one such moment was Yatora and Yuka talking after Yuka gets dumped in the park. That conversation was pretty important but the bgm felt like it was there because there had to be a bgm.
