May I ask you to work on the Cyrillic a little more? Please, make Д longer, unify the tails of д ц and щ. Make Ж Ф Ш Щ wider, З Г narrower. Make kratka over Й more massive. Make У smoother. Add the rest of the Russian Cyrillic alphabet Ё Ъ Ъ Э Ю Я. Thank you in advance.

Or make your font clonable.

Much better, but kratka (over Й) still needs be heavier. Look at Д, it needs to move to the right to more symmetrical and it used to be better when the right tail went under the vertical, I wanted this for Ц Щ. I also liked the old version Л, although it accepted in some heavy old-style sans-serif fonts. Also the У can be different, and usually the left side has a greater slope to compensate for the tail. The letter Ф used to be made more square, but in your version it's also good, if only to make the place of joining to the vertical heavier. З is worth turning over, it does not have to have a low horizontal. Ж is still narrow and usually does not differ from К.
