Nice repro work! Cream ground really gives a more mellow look perfect for older styles of art. The images look intriguing, sorta like a cross between regular playing cards and the Tarot de Marseille, especially in the Leaves and Acorns suits. The arrangement of the leaves and acorns remind me a bit of Ogham.
Regarding the colors, I think they look great. Not too stark, but defined. That's always a problem with doing reproduction works - like, should you stick to the original colors the artist used (which were originally bright and gaudy but faded over time), or should you give it a faded, worn look as a nod to its vintageness.
