Welcome.
I responded to your proposal at Talk:Stalinist_architecture. The article remains poorly sourced, but that's the nature of the subject. As for your entries on the article, two words of note:
- Inclusion of socialist realism under See also is doubtful. The link has already appeared in the text and its subject is only tangential to the topic.
- Removal of the Lions House characteristic is correct (unsourced qualitative statements, weasel wording) but the characteristic itself is actually correct.
