Not my cup of tea, but the design is stylistically pretty strong. A few of the characters could use tweaks though. For example, why is the 1u mushroom so much bigger than the 1u sausage? There's room to give the sausage a little less left/right padding. And the ~ on the #~ key looks a little blobby.
I really like the function keys. They look nice, and it's a great idea to make them just numbers, but so stylised that they won't be confused with the regular or numpad ones. However, with their symmetrical, geometric styling, combined with the color, they don't match the rest of the set at all.
