Set looks amazing - love the unique vibe the colors give off, and appreciate adding the brown novelties. Are the brown novelties going to be a separate kit? Also is there a reason why some of the graphics (e.g. "Create") aren't on the brown novelties?
On the subject I'm actually also wondering why there are so many light/tan novelties when there aren't any light/tan mods in the kit. The only situation when I can see someone using the tan novelties are with the base+oxidane kit (dark keys with light accents) - and even then they're probably only going to be using the Esc & Enter keys as accents and not the other R2 & R4 mods. Otherwise if they just have the base kit, having only some of the mods in the alpha color looks a bit weird. If you can only do 2 colors in the novelty kits then I would recommend the blue and brown since those are your primary mod and accent colors; or maybe keep the blue novelties as-is, and scale back the tan & brown novelties to just include the Esc/R1 and Enter keys, since those are mainly going to be used as accents anyways.
Anyways just some thoughts to consider.. don't mean to sound overly critical or anything but just want to see this set succeed since this is one of the first sets where I'm actually interested in potentially getting the novelties as well; but the way the kitting is looking right now I'm not 100% sure.
