Thank you for your feedback. I take this seriously, but I'm not familiar with it yet, but will be happy to look into it.

tommai4881 As I said, I had just started without any knowledge of Vietnamese customs. That's why I'm eagerly awaiting your review to the first results pictured here and in the preliminary otfs zipped and attached.

Hi. I'm not the author of this issue, but I'd love to give some feedback. I'm a native speaker of the Vietnamese language, and I'm also familiar with the technicality of the writing system in type design.

In general, the readability of the accents is pretty good; I did not have much trouble reading words. I'd say each letter would be easily recognisable and readable by the average literate reader.

However, to be a little nitpicky, I think there are issues with the design choices and legibility.

1. Design of the hook in the black cut looks very thin when modifying a letter or stacking with other diacritics. Its width should closely match up that of the circumflex, or at least closer to that of the normal letters, although it should not be too thick.

2. Slant angle of the acute and grave accents when used with the circumflex is not as pronounced. Uppercase letters are fine, but the lowercase could be improved. I recommend doing exactly what you did with the breve mark, but with only a slight change to the angle so that the letter wouldn't be too tall.

3. Position of the grave accent in the circumflex-grave combination, especially in the lowercase letters, can sometimes collide with the letter before it. And because of the slant angle problem, the collision is even more noticeable. I'd say move it to the right, since most letters that can follow them do not have ascender strokes on the left.

4. Contrast of the breve mark could be a bit higher, meaning either the bottom is thicker and the two ends are thinner, or the opposite. The low-contrastness of the breve, at this moment, looks very off in the context of a serif font, which, in this case, has a large thickness difference in horizontal and vertical strokes.

5. Stacked combining marks in uppercase letters can be condensed a bit in order not to collide with text from above, as well as to appear visually balanced and synchronised with other accented letters from the same line.

These are the issues that I find the most problematic. Nevertheless, you definitely had a great start, and I believe it will get a lot better. I'd like to see how you'd improve on this.
