I have to say that you have successfully interpreted earth as a human. I like you chose her to be a woman. Maybe on a next version you could also include some of the ecosystems present in earth. Rainforests, beaches, mountains and deserts for example.
Keep drawing and sharing.
Thanks and i actually thought about including some of the ecosystems, but i had already started colouring at that point, so i just ended going with the more simple design. I might do it some other day though :)
