Oh my, now that is much more exciting all close-up like that. I would still agree with Nicolai that serifs are a bit too beefy in contrast with the other details.
Thanks for your comments. While I appreciate Nicolai's amends I really wanted to have a powerful slab serif on this font to make strong horizontal emphasis, I have attached a use of the ligature, I am still in the process of amending. Tim
