Hey Charlie,
Got some nitpick comments on a couple of the input icons 
Not important in the grand scheme of things of course.
The one for the login action looks more like a ‘connection’. Perhaps something like https://fontawesome.com/search?q=login better symbolizes the login action?
The hush icon here is cool actually, but not as recognizable as the more often used lock or key icons, like https://fontawesome.com/search?q=password
Perhaps a circle-dot style icon is more appropriate for the radio input? https://fontawesome.com/search?q=circle
