I would darker the script even more. I'm sure it looks great full size and would print correctly, but it's really blown out on screen. Maybe it's just my computer???
I agree with Monica on spacing the didot out a bit. I feels kind of squished and overwhelmed to me. I love both colorways but think the type pops more in the white on color version so I guess it depends on what you want the focus to be.
Nice. Really clean. Needs space for a time/venue in there somewhere, but that could probably just be added on an extra line without interfering with the simplicity. Love the black and white.
