I love this image.
If you came up to me today and asked me to draw you a butterfly, my priority would probably be symmetry. Make sure the left looks like the right.
These butterflies... Well, they have an equal likeness, but they are not symmetrical. And I love it.
Especially the middle butterfly - I love how the curves mirror each other. Childhood drawings are amazing. They capture the world in a way we struggle to feel free enough to do again. There is no regard for rules, it's just drawing because we want to.
And you know what? I even remember the pen I drew this with.
