Agree on o. Like in Толстой, you can see it’s disconnected, but if you were to start it and go counter-clockwise, you would go full circle, then slightly continue on again through the bottom half of the letter and end and connect to next on the bottom right of the letter rather the top, which is a more natural connection to л

And for Ш in Шостакович, Шотландия: it’s ok, but rather uncommon, it looks like an English W, ie missing the last connector. [imagine flipping this - JJJ - along vertical axis, if that makes sense]

Otherwise very very good, these are nitpicks honestly, it’s very legible and neat anyways
