Okay first off i'm literally like, in love with this design?? i love love LOVE the colors that you used for his artwork both the original colors and the other with the purple tinted pallette.
The light blue details work wonderully in this design and his outfit's just so goddamn cool. especially the pattern on the sleeves.
Now onto the character bio.
The whole species concept is literally like so fun and creatively explained. And i can totally see how it influenced the design choice.
I love how he's just a wee little explorer that goes on adventures :]
Also i can totally relate to that one trivia bit where he gets too excited and just accidentally combines words together that makes no sense. Happened to me a couple times before too.
I love characters that do stuff like studying stars too and that he gives them lil nicknames is literally the cutest thing
