In terms of character design, it’s Lycoris Recoil and Too Many Losing Heroines for me. The girls look so cute.

Shoutout to Imigi Muru, who turned out to be the character designer for both of these series when I went to check. No wonder they look so similar!

If I have to take everything into consideration, then my pick would be Pokémon: Dragonite and the Special Delivery. It’s just so beautiful.

That, or one of Shinkai Makoto’s more famous works (e.g. Your Name).

Edit:

Can’t believe I nearly forgot about Poketoon. The artstyle of the latest episodes is just so cute, so pleasing to the eyes.

The Tale of Princess Kaguya was done in charcoal, which I really loved

Redline was just fun

Hidamari Sketch, Nichijou, Sayonara Zetsubou sensei. And moe styles in general.
