You've got a duplicate r4 PgDn. I assume the one next to the numpad was supposed to be an equals symbol. I also can't find an F13 anywhere.
IMO the novelties don't really look good and feel out of place. I understand what they're supposed to be and definitely think you can make the idea work, but I don't think the current ones compliment the keyset well. It just looks like you took some royalty free "minimalist" images and slapped them onto your keyset because you wanted some novelties. The ANSI Enter stairs in particular look jarring.
