Why do you feel a need to emphasize the number keys and the section sign by giving their characters such a disproportionately large size than other keys? And why do you feel a need to deemphasize the function keys by giving them such a small font size? I very much dislike these choices.
I can't really tell if the numbers are in a different font than the rest of the keys, but if they are, I'd dislike that too. Please use a single font for the whole keyboard.
Aesthetics are a major selling point for your keyboard, so I think you need to spend more time and get expert advice about the fonts.
Finally, this is evidently a Mac-oriented keyboard, given how the control keys are labeled. If you plan to target the Windows market, you may wish to provide layouts with Windows-oriented control keys that are labeled as such (namely Ctrl, Alt, and the Windows key, or something that looks like the Windows key.)
