Historical references in typeface design
I replied that the quality of typeface shapes will gain a lot by looking carefully to historical sources, even not their contemporary interpretation: So rather than looking (as example) at the beautiful Austin by Paul Barnes it can be better to review the sources such type specimen and books set by Richard Austin and John Bell.
The best way to find our way as typeface designer is to built our own unique history, roots, unique references, based on a melting pot of elements. Avoiding looking too deeply today typefaces is a fundamental attitude to keep a certain fresh eye and vision. References should be always indirect and built from an internal maturation.
