As I know you, you like constuctive criticics!

In my opinion C and G are too long in the upper length, the S/s looks different/better. I do not understand j and x. m/w looks a little bit sad. Maybe you can adjust the glyphs (latin/cyrillic) a bit in width?
Noticeable are the numbers 7/3 and the small letter z - as well as 1-5. They are a bit out of line with their curves and their mids.
Unfortunately, the forms do not open up to me, although the "rest" of the Alhpabet (Latin/Cyrillic) seems quite modern and balanced. Also, the V/v looks a bit too wide and massive in comparison to U/u and W/w,  M/m. The proportions do not seems to be quite right (the perpendiculars), even though they may mathematically have the same width. Why is (Cyrillic small letter yu) ю so shapeless and crowded (disproportionate) to the rest? I thought, this very alphabet is very important to you. You may want to rethink the width of the letters for a more harmonious look.

Does the lower case j really need a dot. I think I like it better without.

I would not recommend putting two or more alternates in the same glyph... )If you put 5 alt. й's in one glyph, it would display as ййййй, not й...)

Someday I'm going to make a font that is a group of beautiful letters, every one a different  style and size ;)
