So apparently I told my brother that I could draw a decent aquamarine in two minutes, and he didn't believe me.
This is me not trying.
This is me trying Dx
My brother started laughing so I threw a pencil and paper at him, then timed him for two minutes.
He has created Arnold from "Hey Arnold!" If you didn't grow up watching that show, then you wouldn't get the joke.
And yess, aquamarine is a character from "Steven Universe".
I'll post a separate book about Steven Universe if you don't like the show, or you just don't watch it.
