Just my two cents on the matter. 600x600 is FAR too small for ANY artwork and it generally forces so many details to be missed. I know viewers can click the "download" button to see the full original resolution of an artwork, but I'm more than certain most people will just glance at an artwork then move on to something else without actually putting the effort to click that button first.
