Hey ana this is really cute! For people who like pastel purples or lavender this will be a great option. The deskmats are also cute and can stand on their own (but I'm hoping the final print versions don't have the "oceansetups" branding).
A few thoughts on kitting. Right now your 3 key 40s support forces an accent enter, but has no accent R2 esc. I recommend either adding the accent R2 esc or making the enter mod-colored. Also numpad 00 is unlikely to meaningfully increase the cost of this kit since it's already so large, so I'd consider adding it. The novelties have a solid number of options for being part of the base kit, though you could cut 1 or 2 of the accent 1us if you need to trim.
My only other recommendation is personal-preference based: to vertically center caps-lock and shift icons. Since you're working in dyesub there's nothing forcing the GMK-style placement.
