Key wise, you have two duplicates in the non standard kit (~/‘ & |\). I’d also recommend changing the 3 1u Ctrl/Fn/Alt to Ctrl/Alt/Alt/Ctrl.
Personally not keen on gradient sets, but I think the colors work well together.
Thank you, Xondat! You're very right about the duplicates. This is my first keyset, and I'm using the template MD used for their contest. Still figuring things out. Why do you recommend changing out the 1u keys in the non-standard? Again, this is a template provided by MD (aside from the alt colors and mac/win), and those are the keys in their template, which covers a variety of non-standard boards, as far as I know.
Again, thanks very much for the feedback!
