It takes a hell of a lot of time, I did use vectors for the planet/moon/suns, and mirrored them onto the water manually, but everything else is hand
I use SketchBook Pro draw it, and I use a Wacom Intuos Pro as a pen tablet, lmao tbh it started being quite fun making these.
Omg I love the cartoon-y feel to it but also the kind of realistic-ish thing going on too! This is so awesome!!
