I like the design a lot - but there's one element that just looks way too out of place for me.
The Ace of Spades on the Airplane deck - why did you make the face that of a horned devil skull? It doesn't fit the theme very well to my eyes. I would think a "daring young man in his flying machine" would have been a better choice. Is there a specific, thematic reason for choosing that image?
A word of advice - make it clear to people that clicking on the images will send them to a blown-up version on a new page. I don't see many KS projects offering close-ups like that and it gives people a chance to really see the art details up close. It could convince a fence-sitter to become a backer.
Hey, for the bonus limited-edition deck - are you making a jet-flight deck? Or perhaps even spaceflight?
