I'd humbly suggest changing the $14 million Enter key to a pencil (pointing left), since that's more iconic, and the length of it fits the shape of that keycap better.
Then change the original pencil novelty key, to either a book (evocative of the opening scene of John Wick 2), or the iconic coin/bloodoath marker.
Also surprised there's no novelty, for just a basic bullet.
I'm mixed about the colours. I like that it's evocative of the glock/combat theme, and unique.
But at the same time, I'm pretty basic, and would probably prefer the tried and true black and white theme (aka the suit) with potential for red alternative accents (blood).
