I hope others reading this can catch how amazing it is that there are such layers in so few words.
My first impression (besides damn this is good) is much like the old Is it two faces or a vase? drawings.
Is this happy or sad? I’ve already read it multiple ways. I’m glad it wasn’t forced in one direction or the other, because this is more than one color for more than one set of eyes.
If it was intentional (which I’m pretty sure it was), very clever. If it just happened that way then you have a very sneaky muse to thank :)
