Because of the lesson described at the Primer-book I tried a tile with crescent moon and printemps only. Because I like Printemps but crescent moon isn't one of my favourites. I like to draw it but not its look. So I tried to change it a bit to be more pleasant to my eyes.
It isn't shaded yet, and I'm not sure that I will shade it at all.
But I think I will try this crescent moon/printemps combination again on an other tile.
