I like this colourway a lot! The icons work very well, too.
Just wanted to make sure you're aware that SP doesn't have Row 4 Shift moulds for the 2.25x and 2.75x keys. We've been requesting them for ages, but all the fully sculptured sets that have run so far have been run without them. Matt3o has mentioned that there may finally be something happening about this, but AFAIK they still don't exist.
A suggestion has been made that all SA keyset designers boycott SP until they make the moulds, but this requires a coordinated effort among all the designers, which is no easy task. Considering Carbon sold over 600 base sets, it's a big chunk of business they'd be losing out on if nobody ran sets until they'd done their part. And they'd get more sales afterwards as I know there are some who haven't ordered the fully sculptured sets due to this issue.
