I like the way you break up the intro of the original article into different sections.
A clear structure
Well defined sections that flow well together. In attributions, I think you could spell it out more explicitly that it was the silver gilding that was added to the vase, and generally the concept of Spolia
Balanced coverage
Looks good! There are more details about the physical description of the object than history or provenance of the object, but that’s because there’s more information about that.
Neutral content
I would change around the wording about the “raptor” source, adding more specific examples of which other birds it might be modeled after. Also the current wording makes it seem like an Eagle is not a type of bird of prey
Reliable sources
Looks good! I hadn’t even thought about using sources like dictionaries to explain in further detail things like silver guilding.
