I know that the designer made the numbers in this piece so huge and graphic for a reason, but I don't find it successful personally. I don't know how I would change it, maybe make it smaller, or the type on the bottom larger.
Was there an initial idea behind the development of Qalto? Qalto is intended to be a musical typeface. The initial idea was to achieve strong visual rhythm. Regular faces are built on a baseline and an even height.
