It's good but not my favorite. Of course i can appreciate the ideological symbolism there, but stylistically i prefer something that is a bit different from the classical western European aesthetic style, a style which you can very clearly see in the Родина-мать statue, whereas i feel like other Soviet works of art tried to develop a distinct socialist style.

I also really like how the socialist realism style looks in murals, mosaics and reliefs.

As for poster art, there's just too much to choose from, but here are a few i found recently:

I like the internationalism in this one

This one just encapsulates optimism for the future

And i appreciate how this one highlights industry and agriculture

And really we should also not forget to mention music as another form of socialist art, but again, way too much to choose from there, best left to a separate post.
