First, and very important - remember to include a link to the project,
like THIS ONE! Overall, I think you have a rather attractive project here, and the price point is pretty good for today's market, particularly for lots of two and three. But I can point out a few things that might be better.
Speaking of press, who is your printer? Collectors will want to know. Some printers are considered top-notch, others not so much.
Speaking of limited quantities, how many decks do you plan to have printed? It's another thing collectors look for. Some are all about the rarity - the harder a deck is to obtain, the more it appeals to them. It's important for the uncut sheets as well. People want to know the rarity of the items you are offering.
I like the back design and the faces, but there's a problem. The "faux bamboo" effect makes your cards a one-way design on the backs. A one-way back design isn't the end of the world, but they do tend to be less popular and avid poker players won't use them at their table because they can be used for certain cheating techniques. It's even possible, depending on the level of variance from card to card, that the design could be used as a sort of marking system, allowing identification of cards when face down. I would recommend a bamboo- or cream-colored background instead.
If you really want to retain the bamboo effect, keep it for the faces and make it fade out just before the die line. Alternately, if you made the bamboo surfaces 100% uniform and radially symmetrical, then you can use it confidently - but I'd still consider the fade at the deck edge. It's actually a very attractive effect, the most notable examples being the Black Stingers and Red Stingers made by Theory11.
I know the temptation is strong to make your index values look vaguely like kanji, but try not to sacrifice clarity for the design aesthetic. A few less extraneous details on the K and Q would help. It's important for indices to be clearly and quickly understood.
I LOVE that boxed set. Gorgeous. That should be a big draw for backers.
