If your relying on regime “news” sources for your information then its not hard to see why you think Ukraine is “doing well” and Russia isn’t.
Doesn’t change the fact Russia can turn off the lights in Ukraine with impunity.
Your article was from a regime news source.
Here’s an article from your preferred news source (AFP) describing events in the last 24 hours. According to the Russian source quoted in the article, Ukraine put out the lights in his city of 330,000. So it appears Ukraine can also turn off the lights with impunity. Oh, and destroy key and very strategic bridges. So is that also a sign that Russia is winning?
