I was mostly doing it because I thought it looked nicer, to be honest C= Is it convention to put keep labels straight wherever you have room for it?

For more comfort to read them, pretty much for the city/town labels , since they go along with icons and you don't have to use curves and kerning. You can use curves for them only if that's necessary if ever you don't have enough room to put them straight.

Aha, I did not know that! I shall tweak them accordingly.
