Despite the claims coming from pro Ukraine sources about Russian failures and losses, I can only go by the verified information and the footage that is being put out to support it.
There is definitely a steady stream of territorial gains in the Donbas, slow no doubt as it may seem. Footage is relatively scarce, due to the Russian military ban on its forces using and uploading smart phone footage, so all there is, comes from the National Guard and the local militias.
Increasingly the volume of highly graphic content is coming from captured/overrun trench systems which are often full of the corpses of Ukrainian servicemen.
As losses in the field mount, the propaganda war gets more volatile and shrill and correspondingly, unconvincing. So much of the current media output tells its own story by dint of that very fact.
