Tiny problems.
Getting Master on the first try was easy enough; however, there were a few tiny problems. Clicking on the EXACT pixel on Brugel's Landscape with the Fall of Icarus is annoying as hell. Also, Paolo Veronese was a Mannerist painter directly after the Renaissance. Finally, the two bonus Leonardo drawings were the both the some of the less impressive drawings of his, and the gallery didn't need more Leonardo. Your chronology was also a little fussy, and your exemption of Renaissance sculpture was really disheartening.
However, this was a fun little quiz to refresh me on my (admittedly rusty) knowledge of the mid-to-late Renaissance, and it's nice to see something resembling culture on this site.
