One poster likes having the font for expressions look more like the dynamics, and another (like me) likes having them different enough to stand out (I still want a somewhat similarly styled p and f, etc. but not exactly the same).
Usually the expression font is "the same size” as the dynamics - what I mean is, an “m” in both would have the same height.
Looks like these are all 10 point - make the expression 12 point? Worth a try.
I agree about moving the text lines closer together, and where possible, closer to the music.
The same with the dynamics, closer to the staff where you can.
Getting more white space between the lowest line of lyrics for one staff, and the dynamics for the one below is going to help.
I wouldn’t be atypical to have everything aside from the “mf” that’s on the accented note much closer to the staff. The mf would “pop up” out of the plane of the rest. It has to because of the accent, but it’s also forcing everything else up because it wants to try to keep everything on the same plane.
Otherwise, the staves may have to come apart a bit more…but hopefully you get things closer to their respective staves and that’ll help.
