I can't speak to morale necessarily but from what I can see, Russia and the republics have been making most of their gains in the south and east as of late. It's mostly been in the form of advances to villages and taking them in a slow (but still like, 10+ kilometers per day) march towards the inner cities like Dnipro. Supply routes are limited to the main roads, so I imagine that's a focus for Russia to take over. There are Ukrainian strongholds dotted around but the Russians don't seem particularly interested in taking them by brute force, but rather encircling them and starving them of food and ammunition until they surrender.

Reliable information of Kiev and the other major cities is scarce at the moment; Ukraine is suggesting outlandish and purposefully vague victories around the cities. In the last day or two Ukraine has verifiably recaptured a couple towns and villages but the general trend continues. Urban combat is very difficult, so you may as well just put your army around it and wait for their surrender. Which is what is essentially happening, but the fact that the Russians aren't going in and toppling every building and firing missiles at every populated area gives the false idea of a massive Ukrainian resistance that is holding back the enemy forces.

The superiority of the Russian forces is pretty evident from the fact that they aren't needing to put in their entire army, nor use their most modern technology aside from NATO deterrence or the odd operation here and there, nor the fact that they haven't just carpetbombed entire regions.
