Russia has an interesting new vernacular and classical scene with lots of creativity aswell as clumsy pastiche. Most higher quality projects except church buildings are in Moscow, Sankt Petersburg and Kazan. What is interesting is the ongoing experimentation with facade decoration using modern techniques. Many projects take inspiration from Art Nouveau, a style that seems especially beloved in the country. A big problem for many Russian projects is that they are oversized since municipalities fail to restrict height and scale in a good way.
Ukraine has a great demand for classical architecture but few classically trained architects. While there are good projects, in general most are simple historicist inspired.
