Wow, it looked awesome. Sure, you can color it if you want, but remember that their hair are dark blue and their eyes are piercing light blue because they're not Asians from Earth but from the planet of Lusteria. It's kinda like in the world of Avatar where benders or other Asians can have different eye colors like amber or green...you might want to flip the image after or before you color because you accidentally drew Kyochi's cape on his right shoulder when it should be on the left. Other than that, this is awesome!
My spring break is starting soon so I think I can squeeze my art trade to you somewhere during that time.
