Nice import! I created Wikidata:WikiProject sum of all paintings/Collection/Victoria Memorial. Things you could do to improve it:
- Also include the retrieved date in the reference
- Add a description in the form "painting by <name>". This will also trigger my bots to try to find the creator
- Add described at URL (P973) to all the paintings
I hope you will be importing more collections from http://museumsofindia.gov.in/repository/home . I see you already expanded Wikidata:WikiProject sum of all paintings/Location/India! If you need any help or advice, just let me know.
