Looks great! I like your colors.
I have a couple changes that you should consider making.
Please add a modifier color `~ key as well as an alpha color \| key.
A modifier color ESC key please.
Also, consider text for pg up/pg down/menu so you don't have a mix of icon/text.
I think the star on win key is okay because it has to be neutral.
You need a 1u + [plus sign] key for numpad for 1800 layout.
That's all I can pull off the top of my head. Just got off work!
