Dear Dmitriy Sychiov: Again I am honored that you have chosen one of my fonts to complete with Cyrillic characters. This is an important alphabet that I try to incorporate into some of my fonts, you know, and for that I really appreciate all the advice on Cyrillic glyph design that you kindly give me in your comments. Therefore, with the intention of improving my design of these characters, I dare to present you some suggestions here, I will try to present it in an orderly manner: 1) I like your design of the 2nd Б sans serif better, the same thing happens to me with Г. 2) For Д I like a curved upper part and a lower part with the extensions straight, not curved. This also works for Л -see 1 and 2- although here you will see that I doubt a bit. 3) I have redone З giving it more interior space and drawing its upper left part straight. The same goes for Э. 4) The middle part of Ж must be narrower, as in your 2nd version. 5) The Й that I like is the 2nd, but tilting the inner part of the kratka. 6) For your 2nd Ф I would just add that the central line continues up and down to complete the endings of the glyph in a slanted way. 7) The Ц that I like is the last one you've done, with a straight ending; same for Ш and Щ. I add a sample with those details. What do you think about all this? Knowing your opinion would help me a lot. Thanks in advance.
