The razor-wire at the bottom for Starry Night was clever, and very Grok. Really shows its military spirit.

Edit: I just don't see the point of redacting the Mona Lisa

I read the balls as “houses”, though the phallic spire emerging from them dead-center is also very on-brand

I must admit, I have a natural tendency to overlook C&Bs, but solid catch -- it's there. Perhaps that explains the Mona Lisa redaction; Grok probably put more effort into that one.
