Beautiful design, I love this palette and the ocean theme sooo much! ♥
I decided to write here what came to my mind when looking at the character. I love them very much already ;;;;

I'd call them Daeyang. It means "ocean" in Korean (대양).
Yes, very simple and not too original, but the Korean language somehow gives me vibes of calm and gentleness, and this character just evokes the same feeling!

I dream of a character with this kind of aesthetic, I especially like this slightly pastel but a bit muted oceanic design. It gives me a feeling of purity, freshness of mind and pleasant emptiness, calmness and gentle waves. Very comforting!!
I'd love to make them my web sona or internet sona or something like that???
and draw them ofc when I want to feel that nice freshness and calmness of the ocean. I think this design works very well with anxiety and bad thoughts, like saying:

« you need to slow down, take a deep breath and calm down, listen to the silence and understand that everything is not so pressing,
  if you don't give so much importance to that things »
