I like it very much. The ascenders reminds me of Zapfino.
I find the alternates clever and surely they improve legibility.
(but to find out if they improve readability too, it would be necessary to see a non-lipsum text)

Keep up the good work!

This is really good. I suggest swapping the alternate W with the basic W.

It's been 9 months until I upgraded this. I hope someone will give me an advice.
I reset kerning and redesigned character design according to riccard0's advice. Thank you very much.
Now it has wider spacing and natural flow (If you look at the word American, you'll see the difference).
However, I did not want to redesign the i dot.

Thank you eliason.

I am pretty sure that strange looking small r variation is not my invention, but I learned it in calligraphy class.

All right, it looks like everyone is feeling odd about i. Actually I also do a bit (I felt that i is leaning too much).
I redesigned not only dot but stem too. Obviously this change was adapted to every ligature including i.

In order to vary ascender characters, first l of ll ligature is shortened and d is very slightly shortend as well.
Overall, I exepct designers to utilize Opentype feature as I already prepare several variation for each asending characters.
Each of them has at least three other variations with the exeption of f.
Right now, if the ascenders or descenders of f crashes, there is no way to avoid it.
I think f should be made shorter from the very start so that it does not crash.

This is beautiful stuff. For ll the one with left shorter. And I looked at you previous post, and noticed that bl should be similarily ligatured also.

But you should consider that i; it's just confucing with all European languages with accented glyphs. You don't have to use a round dot, use stem width.

Thank you all.

I designed new i dot but I still prefer previous one despite practical problem. This is probably unquestionable, but which one should be the standard if you would contain both?

Also, I added f alternates thanks to riccard0's clever idea (Thank you very much!). I think these characters solve not olny the problem formerly mentioned (middle row), but others like the crash of gf or pf (bottom row) which seemed to be unsolved.

which [i dot] should be the standard […]?

The longer, more calligraphic one, because it’s more in line with the overall feeling of the typeface, regardless of its possible uses.

You should be able to attach it to the initial post by hitting "edit" near the top of the thread.

How many diacritics do you plan to support?
Can you show us something like this:

Congratulations on the release! :-)
