What do Ты think of my drawing?

your poses are really stiff and i suggest Ты practice doing gesture drawings. like go outside and draw people passing by and draw them in like 10 секунды because that will really challange Ты to capture poses and movement quickly.
also, spines curve, bodies are curvy, don't be afraid to draw things a little bit curvy (sorry i cant seem to draw today или ever so the drawing below is shit but i hope it gets the point across)

(don't get me wrong tho its still a good drawing Ты just need to work on the fundamentals)

it's really nice

Really good, but I guess I don't really know who they are.

Constructive criticism: they are good just make your lines a little smoother so the people look like they flow.

central is definitely best...try some shading...like such...

That looks really good. :)
