This should be a yellow box quiz, otherwise it's just listing artists. You also need to check the answers as you currently don't accept Whistler, van Eyck or El Greco. And some of these are very obscure.
I think the selection of paintings isn't too bad (kinda makes me wonder if you made the quiz to help you with quiz bowl) but yeah I'd correct the spelling of the artists as mentioned above and maybe clarify the year because there are several paintings with some of the names above.
