Okay. First of all, I would like add some details: the green one is pregnant. You can't really tell by the picture. Why am I pointing that out? Well, each drawing has its own story, but some of these stories are hidden. Just the artist, or in this case, the person who asked for the drawing can know. Anyway, art really is an amazing thing. You can discover things with it. As always, you art style never disappoints. I shall stop now before I look like some of those boring art reviewers.
