The lighting in the renders is kind of confusing. Can you show it on a neutral-colored board (e.g. black or gray) and a neutral-colored background? Right now it looks like you took a Necro render, messed with the color histogram in Photoshop, and changed the alpha legends to a a fluroescent pink that probably can't exist as such in ABS plastic. That makes it very hard to judge what it will actually look like.
Also, low-contrast alphas are generally a no-go. You don't want this to be like Chronicler, Soware, KB&Co, etc.
That said, the concept is good and I'm sure people will be into it.
