Im a guy who, when i first saw the madison rounders design, it really turned my crank. So i guess minimalism is my thing. I love using negative space if done correctly, which the jury is still out on concerning this design. I like the flow, but i think i agree with earlier comments that the elements compete for attention.
There's been so much minimalism lately, it's falling into the same category as Cthulhu, zombies, pirates, steampunk, etc. - overused and tired. When Ellusionist is doing it, that's a sure sign that the trend has expired! (No offense to the guys at E, especially since I'm a fan of the Republic No. 02 deck, but they're going a bit more mainstream than a lot of the successful KS designs that have come out.)
It looked to me like you were going more for a classic design, something off of a vintage deck or at least meant to look so. Why not explore some of the ideas from vintage card backs and see where it takes you.
You can find some really good images of
vintage Bicycle backs at Jim Knapp's site as well as from
the other old-school USPC brands.
