Love the thoughtful novelty designs, clearly a lot of love went into them. That said, I'm not sure about your kitting decisions here. Which rows in your novelty kit map to rows on the keyboard? I see a slightly-smaller Earth novelty paired with "Create" - is that intended as a smaller Enter key? Also, novelties typically replace modifiers, so the decision to offer alpha-colored novelties (but not accent-colored novelties) is very unique and worth confirming.
Lastly, the Iron180 is by Smith + Rune, not Nathan_.
Best of luck with the IC!
