When you've painted the rainbow at an angle, disappearing into the horizon, was that artistic license? Because in real life, you would never see the rainbow at an angle, right? At any rate, I love the piece. It's like.... pixelart Van Gogh. Something about the style.

When this started coming together. I thought: These look like Manupix colors.
