As students you have access, among other things, to ARTstore, a visual database of great good resolution reference material for your 3D character or costume creation. (See some examples below *). You can access the site HERE using your Netpass login.
*I took the pictures down because there might be copyright issues, this being an open blog. But login and do your search, you will find amazing stuff. Remember to narrow your search with some boolean operators!:-) e.g. armor AND renaissance, otherwise you will get too many hits
