GRAPHIC DESIGN IS CONFUSING
— Your graphic design is confusing at some point. But I’ll focus on your Moon icon. — It’s better to keep in mind the “traditional” way of seeing things. — People view light-bright with white; and dark-shadows with black. If you’re going to design Moon icons, shouldn’t the full moon be white and the new moon be black? Consider flipping your shading. — Your method of designating waxing and waning is also confusing because you incorporated a diagonal / angled direction in your shadows. People usually “understand” the direction of waxing-waning in a horizontal direction – usually left to right – and not top right to bottom left. — If you do it this way, people will know the difference between “Quarter Moon Waxing” and “Quarter Moon Waning”.
